respiratory system
A system of organs, functioning in the process of gas exchange between the body and the environment, consisting especially of the nose, nasal passages, nasopharynx, larynx, trachea, bronchi, and lungs. It is divided into the upper respiratory system and lower respiratory system. Key words to know: Asthma: a lung disease characterized by inflamed, narrowed airways and difficulty breathing. cystic fibrosis: a genetic disorder that affects lungs and other organs characterized by difficulty breathing, coughing up sputum, lung infections. perfusion: the passage of fluid to an organ or tissue *MORE INFORMATION:* ⦁main functions are the critical tasks of transporting oxygen from the atmosphere into the body's cell and moving carbon dioxide in the other direction. Nasal Cavity - air passage that warms, moistens, and filters air, and also contains olfactory receptors. Medially divided by the nasal septum. External Nares - the visible 'nostrils' that are the entrances into the nasal cavity The Larynx - air passage that connects the pharynx to the trachea, composed of individual cartilages, mostly hyaline. Commonly called the voice box for its additional function of voice production. Epiglottis - the only elastic cartilage, blocks entrance to the larynx during swallowing, ensuring food only enters the esophagus. Lungs - Paired organs that are highly compartmentalized into small air sacs called alveoli. Also contain elastic tissue to facilitate ventilation. Alveoli - the individual lung compartments where gas exchange with blood occurs. ⦁Type 2 cells - cuboidal cells that secrete surfactant, which reduces the surface tension of water to prevent alveolar collapse. Bronchi - the main passageways directly attached to the lungs. Bronchioles- small passages in the lungs that connect bronchi to alveoli Right Lung - divided into upper, middle, and lower lobes by the horizontal fissure and oblique fissure respectively. Left Lung - divided into upper and lower lobes by the oblique fissure, also has the cardiac notch - an indentation for the heart's apex. The Pleurae - a double layer of serous membrane producing serous fluid to reduce friction during lung ventilation/movement. ⦁Visceral pleura - the serous membrane layer that clings to the lung surface. ⦁Parietal pleura - the serous membrane that is separated from the lungs, clings to the internal surface of the thoracic body wall. ⦁Pleural cavity - the space between the parietal and visceral layers filled with serous fluid, which reduces friction and causes pleural membranes to stick together. Perfusion- The passage of fluid to an organ or a tissue. Pulmonary Ventilation - the movement of air into and out of the lungs based on the interactions of pressures in and around the body. ⦁Inspiration - the movement of air into the lungs. ⦁Expiration - the movement of air out of the lungs. Tidal volume - The volume of air ventilated during resting breathing. Inspiratory reserve volume - additional air that can be forcefully inhaled beyond tidal. Expiratory reserve volume - additional air that can be forcefully exhaled beyond tidal. Residual volume - volume of air always in lungs, prevents lung collapse. Medulla Oblongata- the breathing control centers of the medulla oblongata of the brainstem control respiration through monitoring carbon dioxide levels of blood pH. Asthma- A lung disease characterized by inflamed narrowed airways and difficulty breathing. Cystic Fibrosis - A genetic disorder affects the lungs and other organs characterized by difficulty breathing coughing up sputum and lung infections.

Interphase (Mitosis)
BEFORE MITOSIS ACTUALLY BEGINS In interphase, the nucleolus and nuclear envelope are distinct. The chromosomes are in the form of a thread-like chromatin. G1 phase: during G1 phase, also called the first gap phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps. S phase: In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase. G2 phase: the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis. G1, S, G2 phases all together are known as interphase. The prefix inter- means between, reflecting that interphase takes place between one mitotic (M) phase and the next.

Cytokinesis 2 (meiosis)
Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
Cytonkinesis
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. In animal cells, cytokinesis is contractile, pinching the cell in two like a coin purse with a drawstring. The "drawstring" is a band of filaments made of a protein called actin, and the pinch crease is known as the cleavage furrow. Plant cells can't be divided like this because they have a cell wall and are too stiff. Instead, a structure called the cell plate forms down the middle of the cell, splitting it into two daughter cells separated by a new wall. Divides into two identical daughter cells.

Common endocrine system diseases
Hypothyroidism Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormone to meet the body's needs. Without enough thyroid hormone, many of the body's functions slow down. Thyroid Cancer Thyroid cancer begins in the thyroid gland and starts when the cells in the thyroid begin to change, grow uncontrollably, and eventually form a tumor. There are two types of tumors: benign (noncancerous) and malignant (cancerous, meaning that it can spread to other parts of the body). Hypoclycemia Hypoglycemia, also called low blood glucose or low blood sugar, occurs when blood glucose drops below normal levels. Glucose, an important source of energy for the body, comes from food. Carbohydrates are the main dietary source of glucose. In adults and children older than 10 years, hypoglycemia is uncommon except as a side effect of diabetes treatment.

immune system
Immune System - a "functional system" consisting of many dispersed cells and molecules that target pathogens, disease-causing microbes. Innate defenses (nonspecific) - inborn immunity that constantly prevents infection of any target. Adaptive defenses (specific) - form slower responses to specific targets, improves through life. Innate defenses: Surface barriers - skin and ciliated mucous membranes that act as first line of defense. ⦁acidity and toxins of skin secretions prevent bacterial growth. ⦁acidic secretions in stomach kill microbes. ⦁enzymes in saliva and tears kill bacteria. ⦁mucous in digestive and respiratory tracts trap microbes. Innate defenses Internal defenses - cells and molecules that act as second line of defense. ⦁Phagocytes - cells that engulf foreign cells and debris. ⦁Fever - prevents bacterial growth and encourages healing. ⦁Natural killer cells - patrol tissues and kill cells. ⦁Antimicrobial proteins - kill bacteria and prevent spread of viruses. ⦁Inflammation - complex tissue response to injury or infection. Phagocytes - include macrophages, dendritic cells, neutrophils, and eosinophils. Steps of phagocytosis: ⦁Phagocyte attaches to and engulfs microbe, forming a phagosome. ⦁The phagosome fuses with an enzyme-filled lysosome, forming a phagolysosome. ⦁The microbe is digested and waste is removed. Adaptive defenses - the slow but highly specific method of targeting pathogens, mainly via lymphocytes ⦁Specific - certain cells targeting particular pathogens ⦁Systemic - full body, not one infection site ⦁Memory - forms cells to prepare for future encounters ⦁Humoral Immunity (antibody-mediated) - uses antibodies in body fluids to target specific pathogens, primarily bacteria ⦁Cellular immunity (cell-mediated) - uses whole cells to target specific pathogens, primarily cancerous cells and virally or parasitically infected cells B lymphocytes - oversee humoral immunity T lymphocytes - oversee cellular immunity Plasma cells - the B cell clones that specialize in antibody production and secretion, only a 4-5day lifespan Memory cells - a lymphocyte that responds to an antigen upon reintroduction Active humoral immunity - a humoral immune response involving a B cell challenge, producing immunological memory ⦁Naturally - bacterial or viral infection ⦁Artificially - vaccine injection of dead or weakened pathogen Passive humoral immunity - a humoral immune response not involving a B cell challenge, and not memory ⦁Naturally - antibodies from mother to child via placenta or breast milk ⦁Artificially - antibody injections, as in rabies shots and antivenom Antibodies (immunoglobulins) - proteins secreted by B cells that bind to specific pathogens, a single y-shaped protein is called a monomer ⦁Heavy and light chains - inner and outer peptide chains, lengths vary ⦁Variable regions - unique area with antigen-specific binding sites ⦁Constant regions - large region that determines the 'class' of the antibody Cellular immune response - a cell-mediated response triggered by the antigen challenge of a T cell, where this antigen must be presented. Their primary targets are cancerous cells or cells infected by virus or parasite CD4 cells - called "Helper T cells", can only receive antigens presented by MHC class 2 CD8 cells - called "Cytotoxic T cells" because they can kill cells directly, can only receive antigens presented by MHC class 1 Autoimmunity - any condition where the body's immune system uses antibodies and Cytotoxic T cells to target self tissues ⦁Multiple Sclerosis - targets white matter of the CNS ⦁Rheumatoid arthritis - targets joints tissues ⦁Myasthenia gravis - targets ACh receptors at neuromuscular junctions. Hypersensitivities (allergic reactions) - when the immune system responds to a non-pathogenic substance, now called an allergen ⦁Sensitization - first encounter with allergen leads to the production of many, specific IgE antibodies ⦁Secondary response - future encounters activate the antibodies, triggering mast cells and basophils to release histamine. Histamine release causes vasodilation, mucus secretion, bronchial constriction, etc. Anaphylactic shock - when an allergic reaction becomes systemic, can be fatal due to throat swelling and bronchial constriction

Mouth, pharynx, esophagus, stomach, small and large intestines, rectum, and anus.
Digestive pathway
Mouth/pharynx does the mechanical breakdown of food by chewing and chemical breakdown through saliva. Esophagus moves food toward stomach by peristalsis. Stomach does mainly the chemical breakdown of food Pyloric sphincter- The pyloric sphincter controls the flow of food that has been digested by the stomach into the duodenum. From there is goes on to the small intestine, where the process of chemical digestion continues. The pyloric sphincter itself is a muscle. Small intestine- digestion of starches and absorption of nutrients. CCK- a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine (duodenum). Large intestine- absorption of water and salt, concentration of feces. Appendix-It creates the healthy bacteria for your digestive system Rectum- temporary storage of waste before expulsion. Anus- waste leaves the body and the digestive system.

Citric Acid Cycle (Krebs Cycle)
Products of the Citric Acid Cycle Two carbon atoms come into the citric acid cycle from each acetyl group, representing four out of the six carbons of one glucose molecule. Two carbon dioxide molecules are released on each turn of the cycle; however, these do not necessarily contain the most recently added carbon atoms. The two acetyl carbon atoms will eventually be released on later turns of the cycle; thus, all six carbon atoms from the original glucose molecule are eventually incorporated into carbon dioxide. Each turn of the cycle forms three NADH molecules and one FADH2 molecule. These carriers will connect with the last portion of aerobic respiration to produce ATP molecules. One GTP or ATP is also made in each cycle. Several of the intermediate compounds in the citric acid cycle can be used in synthesizing non-essential amino acids; therefore, the cycle is amphibolic (both catabolic and anabolic).

sebaceous vs sweat glands (sudoriferous)
Sebaceous glands and sweat glands are both exocrine glands found in the skin. Exocrine glands secrete substances through ducts to the surface of the skin. *Sebaceous glands* are *holocrine glands*, which secrete sebum: an oily mixture of lipids and proteins; waterproofs skin, protects from pathogens. They are connected to the hair follicles and secrete sebum through the hair pore. -Sebaceous glands are found in most of the skin (except the palms of the hands and the soles of the feet). -The sebaceous glands are located in the dermis, the middle layer of the skin, and they develop from the epithelial cells of the hair follicle itself (the external root sheath of the hair follicle). *Sweat Glands* -Can be Eccrine or apocrine glands -Eccrine glands are not connected to hair follicles, they secrete salty solution made of electrolytes and water but also contains, NaCl, KHCO3, Glucose, Antimicrobial Peptides. eccrine gland: The major sweat glands of the human body, found in virtually all skin, produce a clear, odorless substance, consisting primarily of water and NaCl. The most numerous types of sweat glands in our skin, found almost everywhere on the body, are called eccrine glands. These are the true sweat glands in the sense of helping to regulate body temperature. In other words, sweating causes the loss of body heat and thus cools us down on a hot day or when performing strenuous exercise. This is because as the water in sweat evaporates, it takes body heat with it. Found on: Forehead, neck, back *Apocrine glands ⦁Secrete oily solution ⦁Armpits, groin, palms, soles of feet ⦁Activated by stress or anxiety ⦁Body Odor forms from bacteria feeding on apocrine sweat The other kind of sweat glands are known as apocrine glands. The apocrine glands are found in places like the armpits, scrotum, anus, and labia majora. They are typically larger than eccrine glands and their ducts tend to open into hair follicles instead of hairless areas of skin. These glands serve virtually no role in the regulation of body temperature. These are also the glands largely responsible for body smells, as their excretions are converted by skin bacteria into various chemicals we associated with body odor.

Skin Thermoregulation/Temperature Homeostasis
TEMPERATURE HOMEOSTASIS - skin is involved in temperature homeostasis through sweat glands -Controlled by negative feedback system consisting of a Receptor, control center and effector *Receptor* ⦁Sensory cells in dermis of skin *Control center* ⦁Hypothalamus *Effectors* ⦁Sweat glands, blood vessels, and muscles (help with shivering) ⦁Perspiration- The body also thermoregulates via the process of sweating (perspiration). As drops of sweat form on and then evaporate from our skin surface, they take body heat away with them. All else held equal, the greater the skin surface area and the higher the sweat rate, the greater the rate of cooling via sweating. ⦁Vasodilation - Vasodilation refers to the process of expanding (-dilation) the size of the blood vessels (vaso-). The now enlarged peripheral vessels of the skin allow for greater amounts of blood to flow near the surface of the skin. This allows for our body to release a lot of body heat through radiation. Arrector Pili Muscles The hairs on the skin lie flat and prevent heat from being trapped by the layer of still air between the hairs. This is caused by tiny muscles under the surface of the skin, called arrector pili muscles. When these muscles relax their attached hair follicles are not erect. These flat hairs increase the flow of air next to the skin and increase heat loss by convection. If the body needs to prevent the loss of excess heat, such as on a cool day, it will end up constricting the blood vessels of our skin. This process is known as vasoconstriction.

Alveoli
The air sacs of the lungs in which the exchange of oxygen and carbon dioxide takes place. This exchange occurs by diffusion. Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion in biology: • Gas exchange at the alveoli — oxygen from air to blood, carbon dioxide from blood to air. • Gas exchange for respiration — oxygen from blood to tissue cells, carbon dioxide in opposite direction. • Transfer of transmitter substance — acetylcholine from presynaptic to postsynaptic membrane at a synapse. • Osmosis — diffusion of water through a semipermeable membrane.
amino acid derivative hormones
The amino acid-derived hormones are relatively small molecules derived from the amino acids tyrosine and tryptophan. If a hormone is amino acid-derived, its chemical name will end in "-ine". Examples of amino acid-derived hormones include epinephrine and norepinephrine, which are synthesized in the medulla of the adrenal glands, and thyroxine, which is produced by the thyroid gland. The pineal gland in the brain makes and secretes melatonin, which regulates sleep cycles.

cardiac cycle
The cardiac cycle consists of diastole and systole which each have a first and second phase that occur at the same time. 1st diastole phase -> ⦁ blood flows through the superior and inferior vena cava. ⦁ the heart is currently relaxed the blood flows passively from the atrium through the open tricuspid valve, to the right ventricle. ⦁ The SA NODE (pacemaker of the heart) begins to generate electric signals, which are carried by purkinje fibers to the rest of the atrium which stimulates it to Contract & fill right ventricle with blood. ⦁ The Impulse from the SA node is transmitted to ventricle through AV node which then Signals the right ventricle to contract & begin 1st systole phase 1st SYSTOLE PHASE -> ⦁Tricuspid valve closes and Pulmonary semilunar valve opens ⦁Blood is pumped out of the pulmonary arteries to lungs ⦁2nd DIASTOLE PHASE ⦁Blood returning from lungs fills left atrium ⦁SA node triggers mitral valve to open, Blood fills left ventricle ⦁2nd SYSTOLE PHASE ⦁Mitral valve closes and Aortic semilunar valve opens ⦁Left ventricle contracts and blood is pumped out of aorta to rest of body
selective permeability
The cell membrane only allows small molecules to diffuse through it. Oxygen and water molecules are small enough to be allowed to pass through the cell membrane The IONS on the cell surface help to attract or repel other ions. Like charges are repelled, opposite charges are attracted to the cells surface. Molecules that are soluble in phospholipids can pass through the cell. (such as steroids, alcohols, and some vitamins, can dissolve in the lipid portion of the membrane, which is how they diffuse into and out of the cell) Many molecules cannot diffuse through the cell membrane and must be moved through by ACTIVE TRANSPORT and VESICLES.
What's the difference between Mitosis and Meiosis?

Renal Pelvis
The center of the kidney where urine collects before moving to the ureter
Prophase
The chromatin thickens into chromosomes and the nuclear membrane begins to disintegrate. Pairs of centrioles move to opposite sides of cell and spindle fibers begin to form. The mitotic spindle, formed from cytoskeleton parts, moves chromosomes around within the cell. First phase of mitosis in which duplicated chromosomes condense and mitotic spindle fibers begin to form
Telophase 1 (meiosis)
The chromosomes arrive at opposite poles of the cell. In some organisms, the nuclear membrane re-forms and the chromosomes decondense, although in others, this step is skipped—since cells will soon go through another round of division, meiosis II. Cytokinesis usually occurs at the same time as telophase I, forming two haploid daughter cells.
Saliva
The clear liquid found in the mouth, also known as spit
Types of Circulation
The circulatory system includes: Coronary Circulation, Pulmonary circulation, and Systemic circulation *Coronary circulation* is the flow of blood to the heart tissue. (Pathway of blood flow through the heart) Step 1: Blood enters right atrium from superior and inferior venae caveae. Step 2: Blood in the right atrium flows through right atrioventricular(AV) valve into right ventricle. Step 3: Contraction of the right ventricle forces pulmonary valve open. Step 4: Blood flows through pulmonary valve into pulmonary trunk. Step 5: Blood is distributed by right and left pulmonary arteries to the lungs, where it becomes oxygenated. *Pulmonary Circulation* is the flow of blood between the heart and lungs. 1. Deoxygenated blood from your body enters the right atrium of your heart through the superior vena cava and the inferior vena cava. 2. From the right atrium, the deoxygenated blood drains into the right ventricle through the right AV valve. (When the ventricles contract, the right AV valve closes off the opening between the ventricle and the atrium so blood doesn't flow back into the atrium.) 3. The right ventricle then contracts, forcing the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery. (The pulmonary semilunar valve keeps blood from flowing back into the right ventricle after it's in the pulmonary artery.) 4. The pulmonary artery carries the blood that's very low in oxygen to the lungs, where it becomes oxygenated. 5. Freshly oxygenated blood returns from the lungs to the left atrium of the heart via the pulmonary veins. *Systemic Circulation* is the flow of blood to the heart tissue 1. The pulmonary veins push oxygenated blood into the left atrium. (When the left atrium relaxes, the oxygenated blood drains into the left ventricle through the left AV valve.) 2. As the left ventricle contracts, the oxygenated blood is pumped into the main artery of the body — the aorta. (To get to the aorta, blood passes through the aortic semilunar valve, which serves to keep blood in the aorta from flowing back into the left ventricle.) 3. The aorta branches into other arteries, which then branch into smaller arterioles, carrying oxygenated blood all around your body. (Throughout your body, arterioles meet up with capillaries where oxygen is exchanged for carbon dioxide.) 4. Through capillary exchange, oxygen leaves red blood cells in the bloodstream and enters all the other cells of the body. 5. The deoxygenated blood moves into the smallest veins, called venules, and then into bigger veins until it reaches the vena cava.

There are over 600 muscles in the human body. all muscles have 3 properties in common excitability, contraction, elongate All muscles have the ability to contract and shorten (contraction) all muscles have the ability to elongate or relax (elongate) Skeletal muscles: are Voluntary muscles and are composed of muscle fibers that are bound together in parallel bundles. They are known as striated muscle due to their striped appearance. Smooth muscle tissues: are involuntary muscles found in the walls of internal organs such as the stomach, intestines, and blood vessels.

About Sebum
The sebum produced by these glands plays numerous important roles: Sebum is a lubricant and inasmuch it helps to moisturize the skin. It does so by preventing the excess evaporation of water from the skin. Sebum serves to keep us healthy by keeping in check the growth of certain bacteria on our skin. That's because sebum contains chemicals that kill bacteria. This helps ensure bacteria don't invade into deeper layer of our skin. It helps to condition the hair. Meaning, it ensures our hair doesn't become too dry and brittle. Sebaceous glands are involved in numerous conditions. During puberty, various hormones cause them to produce a lot of sebum and this therefore contributes to oily skin. If a duct of a sebaceous gland is clogged with sebum, a whitehead results. If this material is allowed to dry and oxidize, it will become darker, forming a blackhead. If a sebaceous gland becomes infected, moderate and severe forms of acne are the result. The glands lining the ear canal that produce earwax (cerumen) are called ceruminous glands. They are modified sebaceous glands.

functional types of neurons
There are three general functional types of neurons: Sensory Neurons, motor neurons, and interneurons. 1. Sensory neurons ⦁transmit signals to the central nervous system from the sensory receptors that are associated with touch, pain, temperature, sight, hearing, smell, taste 2. Motor neurons -transmit signals from the CNS (central nervous system) to the rest of the body such as by signaling muscles or glands to respond 3. Interneurons ⦁transmit signals between neurons **Neuron Parts 1. Cell body (soma) ⦁contains nucleus of neuron 2. Axon ⦁transmits impulses away from cell body, is insulated by oligodendrocytes & myelin sheath with gaps (nodes of Ranvier) -terminates at the synapse 3. Dendrites receive impulses from sensory receptors or interneurons & transmit them toward cell body Neurotransmitter: A chemical substance that is released from the AXON TERMINAL by the arrival of a nerve impulse ⦁Diffuses across the SYNAPSE, ⦁causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure at the DENDRITE of the other cell ⦁ Acetylcholine: NT; causes muscle to contract ⦁ Dopamine: NT; precursor to epinephrine

Double loop system of the heart
We have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide. The pulmonary carries DEOXYGENATED blood from right ventricle to Lungs and the systemic carries OXYGENATED blood from left ventricle to the body. The human heart is called a double loop because it consists of two separate loops, the pulmonary loop and systemic loop. The pulmonary loop is the flow of deoxygenated blood from the heart to the lungs. In the lungs, carbon dioxide from the blood is exchanged for oxygen. After this exchange, the blood is directed back to the heart. The second loop is the systemic loop, which starts with the freshly oxygenated blood being pumped by the heart out to all cells in the body to deliver oxygen and nutrients, and to pick up carbon dioxide on its way back to the heart. Blood flow of the heart: If you can't get yourself to remember the blood flow through the heart I would suggest taking a video of yourself explaining the process with a diagram on google! I explain it to myself this way: Deoxygenated blood comes in through the superior and inferior vena cava and fills the right atrium. The SA node generates electric signals carried by purkinje fibers which stimulates the tricuspid valve to contract and open releasing blood into the right ventricle. The pulmonary semilunar valve opens and the blood flows out of the pulmonary artery into the lungs. Once the blood becomes Oxygenated it flows back into the heart through the pulmonary vein and into the left atrium. The sa node generates electric signals again and the mitral valve contracts and opens allowing the blood to flow into the left ventricle. The aortic semilunar valve opens and the blood flows through the valve and into the aorta where it gets released back into the body! Essentially, superior and inferior vena cava > right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary artery > lungs *This is known as pulmonary loop* Pulmonary vein > left atrium > mitral valve > left ventricle > aortic semilunar valve > aorta > body *this is known as systemic loop* Also called the double loop system.

electron transport chain
lectron Transport Chain You have just read about two pathways in cellular respiration—glycolysis and the citric acid cycle—that generate ATP. However, most of the ATP generated during the aerobic catabolism of glucose is not generated directly from these pathways. Rather, it is derived from a process that begins with moving electrons through a series of electron transporters that undergo redox reactions: the electron transport chain. This causes hydrogen ions to accumulate within the matrix space. Therefore, a concentration gradient forms in which hydrogen ions diffuse out of the matrix space by passing through ATP synthase. The current of hydrogen ions powers the catalytic action of ATP synthase, which phosphorylates ADP, producing ATP. The electron transport chain (Figure 7) is the last component of aerobic respiration and is the only part of glucose metabolism that uses atmospheric oxygen. Oxygen continuously diffuses into plants; in animals, it enters the body through the respiratory system. Electron transport is a series of redox reactions that resemble a relay race or bucket brigade in that electrons are passed rapidly from one component to the next, to the endpoint of the chain where the electrons reduce molecular oxygen, producing water.

Cell
!! IMPORTANT !! - *Cytology* is the study of cells. The cell is the smallest living organism. The basic organizational unit of life. All cells have a membrane. All *living* cells contain both DNA and Rna (except some cells such as mature red blood cells), while viruses contain either DNA or RNA, but usually not both. Function: The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Prokaryote vs Eukaryote. Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
Chemical Synapse
*"Point of Contact"* -A substance is released that *stimulates or inhabits* the action of the adjoining cell.
Antigen and Typical Immune Response
*Antigens*: Substances that stimulate the immune system. ~Proteins on the surface of bacteria, viruses, and fungi. ~Drugs, toxins, and foreign substances can be antigens. -Body *recognizes* the antigens of its own cells but it *will attack* cells or substances with unfamiliar antigens. -Specific *antibodies* are produced for each antigen that enters the body.
Active Immunity
*Naturally Acquired*: The individual is exposed and builds immunity to a pathogen *without* an immunization. *Artificially Acquired*: The individual is exposed and builds immunity to a pathogen *by a vaccine*. -Pathogens can enter body through *lymph nodes*. Nodes contain *large number of antigen-presenting cells* (APC) that can trigger the adaptive immune system.
Organ vs Organ System
*Organ* - a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans. *Organ System* - an organ system is a group of organs that work together to perform one or more functions. Each does a particular job in the body, and is made up of certain tissues.

connective tissue
Is dense, loose, or fatty. It protects and binds body parts. Has a jelly-like base and is fibrous. Connective tissues are specialized tissues, which provide support and hold the body's tissues together. Connective tissue is made up of a small fraction of cells and a majority of extracellular substance which keeps the cells separated. The two types of cells found in connective tissue include fibrocytes (or fibroblasts) and fat cells, which are fixed cells. Additionally, the extracellular substance separating the cells is made up of three types of fibers, including collagen fibers, reticular fibers and elastic fibers. Collagen fibers are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix. Elastic Fibers Elastic fibers are long, thin fibers that form branching network in the extracellular matrix. They help the connective tissue to stretch and recoil. Reticular Fibers Reticular fibers are short, fine collagenous fibers that can branch extensively to form a delicate network. Fibroblasts make collagens, glycosaminoglycans, reticular and elastic fibers, Growing individuals' fibroblasts are dividing and synthesizing ground substance. Tissue damage stimulates fibrocytes and induces the production of fibroblasts.

Layers of skin (Superficial to deep)
*Epidermis:* ⦁Most superficial layer of the skin ⦁made of Epithelial cells *Does not contains any blood vessels *Stratum Basale* ⦁Deepest portion ⦁Single layer of cells ⦁Keratinized - waxy protein that waterproofs skin ⦁Creates Skin color (melanin) ⦁Protect against UV rays *dermis:* ⦁Mostly connective tissue ⦁Blood vessels, sensory receptors, hair follicles, sebaceous glands, sweat glands. ⦁Elastin and collagen fibers *Subcutaneous Layer/ Hypodermis* (not a layer of skin) ⦁Connective tissue ⦁Binds skin to muscle ⦁Fat deposits cushion and insulate body Five types of Skin Layers in the Epidermis: "Come Let's Get Sun Burned" (Top to Bottom) ⦁Stratum Corneum: "Top Layer"- Dead keratinocytes ⦁Stratum Lucidum: "Clear Layer"- Colorless protein eleidin ⦁Stratum Granulosum: "Thin Layer"- granular layer ⦁Stratum Spinosum: "Spiny Layer"- Thickest layer, keratinocytes, immune dendritic cells, sensory cells ⦁Stratum Basale: "Basal Layer"- Bottom layer; contains melanocytes. *The Epidermis* The epidermis is a thin layer of skin. It is the most superficial layer of skin, the layer you see with your eyes when you look at the skin anywhere on your body. Functions of the epidermis include touch sensation and protection against microorganisms. This skin is further divided into five, separate layers. In order from most superficial to deepest, they are the: Stratum Corneum Stratum Lucidum Stratum Granulosum Stratum Spinosum Stratum Basale Stratum Corneum - This layer is composed of the many dead skin cells that you shed into the environment—as a result, these cells are found in dust throughout your home. This layer helps to repel water. Stratum Lucidum - This layer is found only on the palms of the hands, fingertips, and the soles of the feet. Stratum Granulosum - This is the layer where part of keratin production occurs. Keratin is a protein that is the main component of skin. Stratum Spinosum - This layer gives the skin strength as well as flexibility. Stratum Basale - This is where the skin's most important cells, called keratinocytes, are formed before moving up to the surface of the epidermis and being shed into the environment as dead skin cells. This layer also contains melanocytes, the cells that are largely responsible for determining the color of our skin and protecting our skin from the harmful effects of UV radiation. These harmful effects include burns in the short term and cancer in the long run. *The Dermis* Underneath the epidermis lies the dermis. The dermis contains: -Blood vessels that nourish the skin with oxygen and nutrients. The blood vessels also allow immune system cells to come to the skin to fight an infection. These vessels also help carry away waste products. -Nerves that help us relay signals coming from the skin. These signals include touch, temperature, pressure, pain, and itching. Various glands. -Hair follicles. -Collagen, a protein that is responsible for giving skin strength and a bit of elasticity. *The Subcutaneous Tissue* The deepest layer of the skin is called the subcutaneous layer, the subcutis, or the hypodermis. Like the dermis, the layer contains blood vessels and nerves for much the same reasons. Importantly, the subcutis contains a layer of fat. This layer of fat works alongside the blood vessels to maintain an appropriate body temperature. The layer of fat here acts as a cushion against physical trauma to internal organs, muscles, and bones.

More Information on haploid and diploid cells!
*Haploid* cells are cells that contain only one complete set of chromosomes. The most common type of haploid cells is gametes, or sex cells. Haploid cells are produced by meiosis. They are genetically diverse cells that are used in sexual reproduction. When the haploid cells from the parent donors come together and are fertilized, the offspring has a complete set of chromosomes and becomes a diploid cell. A haploid cell will have a haploid number, which is the number of chromosomes found within the nucleus that create one set.

Arteries
An artery, as we know, is a blood vessel that carries blood AWAY from the heart. There are many types of arteries. Aorta - the aorta of the heart is a large artery that branches off of the heart to the rest of the body. It is the largest artery in the body. Other types: *Coronary artery* - supplies blood to the heart There is a right and left coronary artery. -The right coronary artery supplies: ~right atrium ~right ventricle ~bottom portion of both ventricles and back of the septum The left coronary artery supplies: ~Circumflex artery - supplies blood to the left atrium, side and back of the left ventricle ~Left Anterior Descending artery (LAD) - supplies the front and bottom of the left ventricle and the front of the septum *Carotid Atery* - The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions: The internal carotid artery supplies blood to the brain. The external carotid artery supplies blood to the face and neck. *Subclavian artery* - There are two subclavian arteries that supply our arms with blood. The subclavian arteries branch to the vertebral arteries. These carry oxygenated blood up to the brain from the base of the neck. *Common iliac artery* - The abdominal aorta divides to form the "common iliac arteries" in the lower abdomen, and these vessels supply blood to the pelvic organs, gluteal region, and legs. Each common iliac artery descends a short distance and divides into an internal and an external branch. *Renal artery* - Your renal artery, then, is a blood vessel that carries oxygenated blood to your kidneys. All of these arteries carry OXYGENATED BLOOD FROM THE HEART TO SUPPLY THE REST OF THE BODY.
Review cellular respiration
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. Glycolysis is an anaerobic process, while the other two pathways are aerobic. In order to move from glycolysis to the citric acid cycle, pyruvate molecules (the output of glycolysis) must be oxidized in a process called pyruvate oxidation. Glycolysis Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules. There are two halves of glycolysis, with five steps in each half. The first half is known as the "energy requiring" steps. This half splits glucose, and uses up 2 ATP. If the concentration of pyruvate kinase is high enough, the second half of glycolysis can proceed. In the second half, the "energy releasing: steps, 4 molecules of ATP and 2 NADH are released. Glycolysis has a net gain of 2 ATP molecules and 2 NADH. Some cells (e.g., mature mammalian red blood cells) cannot undergo aerobic respiration, so glycolysis is their only source of ATP. However, most cells undergo pyruvate oxidation and continue to the other pathways of cellular respiration. Pyruvate Oxidation In eukaryotes, pyruvate oxidation takes place in the mitochondria. Pyruvate oxidation can only happen if oxygen is available. In this process, the pyruvate created by glycolysis is oxidized. In this oxidation process, a carboxyl group is removed from pyruvate, creating acetyl groups, which compound with coenzyme A (CoA) to form acetyl CoA. This process also releases CO2. Citric Acid Cycle The citric acid cycle (also known as the Krebs cycle) is the second pathway in cellular respiration, and it also takes place in the mitochondria. The rate of the cycle is controlled by ATP concentration. When there is more ATP available, the rate slows down; when there is less ATP the rate increases. This pathway is a closed loop: the final step produces the compound needed for the first step. The citric acid cycle is considered an aerobic pathway because the NADH and FADH2 it produces act as temporary electron storage compounds, transferring their electrons to the next pathway (electron transport chain), which uses atmospheric oxygen. Each turn of the citric acid cycle provides a net gain of CO2, 1 GTP or ATP, and 3 NADH and 1 FADH2. Electron Transport Chain Most ATP from glucose is generated in the electron transport chain. It is the only part of cellular respiration that directly consumes oxygen; however, in some prokaryotes, this is an anaerobic pathway. In eukaryotes, this pathway takes place in the inner mitochondrial membrane. In prokaryotes it occurs in the plasma membrane. The electron transport chain is made up of 4 proteins along the membrane and a proton pump. A cofactor shuttles electrons between proteins I-III. If NAD is depleted, skip I: FADH2 starts on II. In chemiosmosis, a proton pump takes hydrogens from inside mitochondria to the outside; this spins the "motor" and the phosphate groups attach to that. The movement changes from ADP to ATP, creating 90% of ATP obtained from aerobic glucose catabolism.

Endocrine functions of pancreas
Functioning as an endocrine gland, the pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day. Both of these diverse functions are vital to the body's survival. The pancreas contains the islets of Langerhans which are made up of insulin-producing beta cells and glucagon-releasing alpha cells. The major hormones produced by the pancreas are insulin and glucagon. Insulin controls carbohydrate metabolism by lowering the amount of glucose in the blood. However, the body also uses glucagon to control carbohydrate metabolism, it has the opposite effect of insulin. Glucagon increases blood sugar levels when they are too low. Both of these together help maintain homeostasis within the body in terms of blood-glucose homeostasis. The endocrine portion of the pancreas controls the homeostasis of glucose in the bloodstream. Blood glucose levels must be maintained within certain limits so that there is a constant supply of glucose to feed the cells of the body but not so much that glucose can damage the kidneys and other organs. The pancreas produces 2 antagonistic hormones to control blood sugar: glucagon and insulin. The alpha cells of the pancreas produce glucagon. Glucagon raises blood glucose levels by stimulating the liver to metabolize glycogen into glucose molecules and to release glucose into the blood. Glucagon also stimulates adipose tissue to metabolize triglycerides into glucose and to release glucose into the blood. Insulin is produced by the beta cells of the pancreas. This hormone lowers blood glucose levels after a meal by stimulating the absorption of glucose by liver, muscle, and adipose tissues. Insulin triggers the formation of glycogen in the muscles and liver and triglycerides in adipose to store the absorbed glucose.

Glycolysis
Glycolysis Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic (processes that use oxygen are called aerobic). Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. Glucose enters heterotrophic cells in two ways. 1.Through secondary active transport in which the transport takes place against the glucose concentration gradient. 2.Through a group of integral proteins called GLUT proteins, also known as glucose transporter proteins. These transporters assist in the facilitated diffusion of glucose. Outcomes of glycolysis: Glycolysis starts with glucose and ends with two pyruvate molecules, a total of four ATP molecules and two molecules of NADH. Two ATP molecules were used in the first half of the pathway to prepare the six-carbon ring for cleavage, so the cell has a net gain of two ATP molecules and two NADH molecules for its use. If the cell cannot catabolize the pyruvate molecules further, it will harvest only two ATP molecules from one molecule of glucose. Mature mammalian red blood cells are not capable of aerobic respiration—the process in which organisms convert energy in the presence of oxygen—and glycolysis is their sole source of ATP. If glycolysis is interrupted, these cells lose their ability to maintain their sodium-potassium pumps, and eventually, they die. The last step in glycolysis will not occur if pyruvate kinase, the enzyme that catalyzes the formation of pyruvate, is not available in sufficient quantities. In this situation, the entire glycolysis pathway will proceed, but only two ATP molecules will be made in the second half. Thus, pyruvate kinase is a rate-limiting enzyme for glycolysis.

The cell membranes of eukaryotic cells and some bacterial cells consist of three types of lipids - phospholipids, glycolipids and cholesterol molecules. Glycolipids are sugar-containing lipid molecules
Key points
Hormones serve as chemical messengers in the body and help maintain homeostasis. Hormones are released into bodily fluids, like blood, which carry them to target cells. Target cells respond to a hormone when they express a specific receptor for that hormone. Hormones also play a role in the regulation of cell death, the immune system, reproductive development, mood swings, and hunger cravings. In the adrenal gland, epinephrine and norepinephrine regulate responses to stress; in the thyroid gland, thyroid hormones regulates metabolic rates. Key Terms target cell: any cell having a specific receptor for a hormone hormone: any substance produced by one tissue and conveyed by the bloodstream to another to affect physiological activity endocrine system: a control system of ductless glands that secrete hormones which circulate via the bloodstream to affect cells within specific organs

Neutrophils help fight infection by ingesting microorganisms and releasing enzymes that kill the microorganisms. A neutrophil is a type of white blood cell, a type of granulocyte, and a type of phagocyte Monocytes A type of immune cell that is made in the bone marrow and travels through the blood to tissues in the body where it becomes a macrophage. Macrophages surround and kill microorganisms, ingest foreign material, remove dead cells, and boost immune responses. A monocyte is a type of white blood cell and a type of phagocyte. Eosinophils A type of immune cell that has granules (small particles) with enzymes that are released during infections, allergic reactions, and asthma. An eosinophil is a type of white blood cell and a type of granulocyte. Basophils A type of immune cell that has granules (small particles) with enzymes that are released during allergic reactions and asthma. A basophil is a type of white blood cell and a type of granulocyte. In allergic reactions, the immune system is exposed to an allergen. Basophils release histamine during allergic reactions. Basophils are also thought to play a role in causing the body to produce the antibody called immunoglobulin E (IgE).

Root: arch
Ruler: tetrarch
Anaphase (Mitosis)
SIMPLE: Centromeres separate; duplicate parts of the chromosomes become separated; spindle fibers shorten and pull individual chromosomes toward centrioles. DETAILED: In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein "glue" that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell. Microtubules not attached to chromosomes elongate and push apart, separating the poles and making the cell longer. All of these processes are driven by motor proteins, molecular machines that can "walk" along microtubule tracks and carry a cargo. In mitosis, motor proteins carry chromosomes or other microtubules as they walk.
Prophase (mitosis)
SIMPLE: Chromatin differentiates into chromosomes; centrioles move to opposite sides of cytoplasm, nuclear membranes and nucleolus disppear; microtubules appear and become associated with centrioles and duplicate parts of chromosomes. DETAILED:In early prophase, the cell starts to break down some structures and build others up, setting the stage for division of the chromosomes. -The chromosomes start to condense (making them easier to pull apart later on). -The mitotic spindle begins to form. The spindle is a structure made of microtubules, strong fibers that are part of the cell's "skeleton." Its job is to organize the chromosomes and move them around during mitosis. The spindle grows between the centrosomes as they move apart. -The nucleolus (or nucleoli, plural), a part of the nucleus where ribosomes are made, disappears. This is a sign that the nucleus is getting ready to break down. -In late prophase (sometimes also called prometaphase), the mitotic spindle begins to capture and organize the chromosomes. -The chromosomes finish condensing, so they are very compact. -The nuclear envelope breaks down, releasing the chromosomes. -The mitotic spindle grows more, and some of the microtubules start to "capture" chromosomes.
Metaphase (mitosis)
SIMPLE: Chromosomes become arranged midway between the centrioles; spindles fibers from the centrioles become attached to the centromeres of each chromosome. DETAILED: In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide. -All the chromosomes align at the metaphase plate (not a physical structure, just a term for the plane where the chromosomes line up). -At this stage, the two kinetochores of each chromosome should be attached to microtubules from opposite spindle poles. -Before proceeding to anaphase, the cell will check to make sure that all the chromosomes are at the metaphase plate with their kinetochores correctly attached to microtubules. This is called the spindle checkpoint and helps ensure that the sister chromatids will split evenly between the two daughter cells when they separate in the next step. -If a chromosome is not properly aligned or attached, the cell will halt division until the problem is fixed. Basically, the the chromosomes (each containing TWO chromatids) align at the very center in a vertical line.
Telophase (mitosis)
SIMPLE: Chromosomes elongate and form chromatin threads, nuclear membranes appear around each chromosome set, nucleoli appear, microtubules disappear. DETAILED: In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place. The mitotic spindle is broken down into its building blocks. Two new nuclei form, one for each set of chromosomes. Nuclear membranes and nucleoli reappear. The chromosomes begin to decondense and return to their "stringy" form.

Simplified Overview of the Heart Cycle
The *ventricles contract* (ventricular systole), causing the *Atrioventrcular Valves* (including mitral and tricuspid vavles) to close, making a *"lub"* sounds. Subsequently, the empty ventricles are filled with blood pushed out during *Atrial Systole*. Same time, the *Semilunar Valves* in the aorta and pulmonary arteries close, preventing blood from falling back into the ventricles, making a *"dub"* sound, and completing the *"lub-dub"* sound of the heart.
cardiovascular/circulatory system
The cardiovascular/circulatory system is responsible for the internal transport of substances to and from the cells. FUNCTION: Movement of blood and lymph around the body, which permits nutrient distribution, waste removal, communication, and protection. The following 3 parts are what it consists of: 1. *Blood* - Blood is made of water, solutes, and other elements in fluid connective tissue. Red blood cells- transport oxygen to cells and form in the bone marrow. White blood cells- defend against infection. Examples of WBC: Lymphocytes, neutrophils, monocytes, eosinophils, basophils. Platelets also play a role in blood clotting. *Sequence of events leading to blood clotting* -vasoconstriction, platelet aggregation, coagulation Plasma makes up half the volume of blood, is mostly water and serves as a solvent, also contains plasma proteins, ions, glucose, amino acids, hormones and dissolved gas. 2. *Blood Vessels* - tubules of different sizes that transport blood. Different types of blood vessels are as follows: Artery, Vein, Arteriole, Venule, Capillary the 3 MAIN types are: Artery, vein, capillary (we will go over this more on separate cards) 3. *Heart* - the heart is a muscular pump which provides the pressure necessary to keep blood pumping.
Endocrine system (Hormones)
The endocrine system is responsible for secreting hormones. The nervous system and the endocrine system work closely together. The hypothalamus (part of the brain) and the pituitary gland (The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain.) coordinate with each other to serve as a neuroendocrine control center. Hormone secretion is triggered by a variety of signals, including hormonal signs, chemical reactions, and environmental cues. Only cells with particular receptors (an organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve.) can benefit from hormonal influence. Steroid hormones trigger gene activation and protein synthesis. Hormones such as insulin work quickly when it is needed. Insulin is a hormone produced in the pancreas by the islets of Langerhans that regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.
Heart
The heart is a muscular pump made of cardiac muscle tissue. The heart has 4 chambers: One half of the heart - -The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. -The right ventricle pumps the oxygen-poor blood to the lungs. Other half of the heart -The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. -The left ventricle pumps the oxygen-rich blood to the body. These halves are separated by a valve called the AV valve which is located between the ventricle and artery leading away from the heart. Valves are important to prevent backwash into the chambers, so they keep blood moving in one single direction. The heart has it's own circulatory system with the coronary arteries. (The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.) The heart functions by contracting and relaxing. These contractions make a sound known as "Lub-dub" The characteristic "lub-dub " sound of the heart is created by the closing of the valves. The "Lub" sound marks the start of the contraction of the ventricles, known as ventricular systole. The sound is caused by the closure of the valves separating each ventricle from its atrium. The two valves are the mitral and tricuspid valves. The tricuspid valve separates the right atrium from the right ventricle while the mitral valve separates the left atrium from the left ventricle. The second "Dub" sound marks the start of the relaxation of the ventricles known as ventricular diastole. The sound is caused by the closure of the pulmonary and aortic valves. These valves prevent blood from rushing back into the ventricles after contraction has occurred. Atrial contraction fills the ventricles. Ventricular contraction empties them. This sequence begins the CARDIAC CYCLE. Heart ⦁Location- in the mediastinum of thoracic cavity. ⦁Function- generates pressure to pump blood through circulatory system ⦁Orientation- flat base is directed toward higher right shoulder, and pointed apex points to left hip. Heart Coverings ⦁Pericardium- the two-layered membranous sac in which the heart sits. Heart Layers ⦁Epicardium- the epithelium clinging to the outer heart wall (is visceral pericardium. ⦁Myocardium- the middle layer composed of cardiac muscles tissue and connective tissue forming the fibrous skeleton. ⦁Endocardium- the epithelium clinging to the inner surfaces of the heart chambers. 4 chambers: 2 Atria, 2 Ventricles Atria- the superior chambers, ear like extensions of the atria, receiving chambers limited pumping means thin walls. Ventricles- the inferior chambers, majority of heart volume, pumping chambers thick walls. Sulci - the indentations on the outer heart surface, correspond between chambers contains fats and vessels. Septa- the internal walls that divide the chambers. Right Atrium ⦁Superior Vena Cava- blood returning from above the diaphragm. ⦁Inferior Vena Cava - blood returning from below the diaphragm. ⦁Coronary Sinus- blood returning from the heart wall. Left Atrium ⦁4 pulmonary veins- blood returning from lungs. Right Ventricle ⦁Receives blood from the right atrium. ⦁Blood exits into the pulmonary trunk to lungs. Left Ventricle ⦁Receives blood from the left atrium ⦁Blood exits into the aorta to the body. **Blood only pass through ½ of the heart at a time, and therefore must pass through the heart twice to complete circulation.
thyroid and parathyroid glands
The thyroid and parathyroid glands are located in the neck just below the larynx. The basic function of the thyroid gland is to regulate metabolism. The thyroid gland secretes the hormones: thyroxine, triiodothyronine, and calcitonin. Thyroxine and triiodothyronine increase metabolism. Calcitonin decreases blood calcium by storing the calcium in bone tissue. the hypothalamus directs the pituitary gland to secrete thyroid-stimulating hormone. The thyroid then releases these hormones as needed via Negative feedback mechanism. -Negative feedback mechanism is the process in which a deviation from normal is detected, a response is made, and the response alleviates need for further action to address the deviation -ex: high blood glucose --> stimulates insulin secretion --> lowers blood glucose level --> inhibits insulin --> raises blood glucose level --> starts all over (continuous loop) The parathyroid glands secrete parathyroid hormone which can increase blood calcium by moving calcium from bone to blood.
Central Nervous System (CNS)
There are two Primary components of the central nervous system: the spinal cord and the brain *Spinal Cord* ⦁encased in the vertebrae which protects & supports the spinal cord. *Brain* (2 hemispheres / 4 main lobes) Consists of: 1. Hindbrain - the hindbrain includes: ⦁medulla oblongata - part of the brain stem, connects the spinal cord to the brain. It is important to the circulatory and respiratory systems. ⦁cerebellum - processing & storing implicit memories/memories developed during classical conditioning learning, also responsible for automatic responses such as blinking when there is a sudden puff of air into the eyes ⦁Pons- also part of the brain stem 2. Midbrain - the third part of the brain stem, above the pons and the medulla oblongata. The midbrain is important for vision and hearing. 3. Forebrain -It controls body temperature, reproductive functions, eating, sleeping, and any display of emotions -includes: Cerebrum: coordination of voluntary activity in the body. Thalamus: acting as a center for pain perception. Hypothalamus:controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.
The kidneys
Urinary System - includes the paired kidneys and ureters and the single bladder and urethra. Functions ⦁Excretion - the elimination of wastes and toxins from the body via urine (regulating water and ion balance and blood volume) Kidney Layers ⦁ Renal Cortex - outer, lighter region where majority of filtration occurs. Glomerulus is found in the cortex. ⦁Renal Medulla - inner, darker region of alternating renal pyramids and renal columns. ⦁Renal pyramids - a bundle of collecting ducts that drain urine from the cortex. ⦁Renal column - cortical tissue between pyramids where blood vessels pass to access the cortex. Parts of the renal tubule ⦁Glomerular (Bowman's) capsule - start of the tubule that surrounds the glomerulus to catch its leaked fluids and solutes. ⦁Proximal convoluted tubule (PCT) - first coiled area in the cortex. ⦁Loop of Henle - long region that dips into medulla, includes descending and ascending limbs. ⦁Distal convoluted tubule (DCT) - second coiled area in the cortex. Collecting duct - tubule that collects urine from many nephrons for transport through a pyramid to the renal sinus. Urine is formed in 3 steps ⦁Glomerular filtration - plasma and solutes (valuable and waste) leak from the glomerulus into the bowman's capsule, forming filtrate. ⦁Tubular reabsorption - valuable solutes are transported from the filtrate back to the plasma of the peritubular capillaries. ⦁Tubular secretion - additional wastes are added to the filtrate from the plasma of the peritubular capillaries. The filtrate is now changed to urine. Color - ranges from clear to deep yellow. Yellowness is due to the presence of urochrome, a pigment from the breakdown of bilirubin. pH - urine is normally slightly acidic, pH near 6, but diet can shift this toward more acidic or alkaline. Urine Composition ⦁95% water ⦁5% solutes ⦁Urea - from the breakdown of amino acids ⦁Uric acid - from the breakdown of nucleic acids ⦁Creatinine - from the breakdown of creatine phosphate ⦁Ions - sodium, potassium, bicarbonate, calcium, H+ Ureter - tube to transport urine from the kidneys to the urinary bladder. Urinary bladder - muscular organ that stores urine. ⦁Lined with a transitional epithelium to allow stretch. Renal Arteries- the two branches of the abdominal aorta that supply kidneys. Urethra - tube that drains urine from the bladder and transports it out of the body. Much longer in males because it courses through the penis. Internal urethral sphincter - smooth muscle structure surrounding the urethra at the base of the bladder. External urethral sphincter - skeletal muscle structure surrounding the urethra in the urigenital diaphragm. Micturition (voiding) - the act of emptying the bladder Micturition reflex: ⦁When about 200 mL of urine is collected, stretch of the bladder initiates the reflex causing contractions of the detrusor muscle and relaxation of the internal urethral sphincter ⦁Relaxation of the external urethral sphincter can allow micturition, OR contraction of the external urethral sphincter can temporarily inhibit the reflex ⦁After an additional 200 mL of urine is collected, the reflex restarts.

Veins
Veins are blood vessels that carry DEOXYGENATED blood to the heart. All of the veins empty into the VENA CAVA prior to entering the heart. Types of veins: *Jugular vein* - The jugular veins are veins that take deoxygenated blood from the head back to the heart via the superior vena cava. *subclavian vein* - The function of the subclavian vein is to empty blood from the upper extremities and then carry it back to the heart. *Hepatic portal vein* - The portal vein or hepatic portal vein is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver before it goes to the heart. *Common iliac vein* - They drain blood from the pelvis and lower limbs. *Renal vein* - There are two renal veins, a left and a right. They branch off the inferior vena cava and drain oxygen-depleted blood from the kidneys.

What is osteoporosis?- brittle fragile bones What causes osteoporosis? Osteoclast and osteoblast What is osteoblast? -Build bone What is osteoclast? - remove bone What is a long bone? - Femur, tibia What is a short bone? - Tarsals What is a flat bone?- Skull Osteogenic cells are the only bone cells that divide. Osteogenic cells differentiate and develop into osteoblasts which, in turn, are responsible for forming new bones. Osteoblasts synthesize and secrete a collagen matrix and calcium salts. When the area surrounding an osteoblast calcifies, the osteoblast becomes trapped and transforms into an osteocyte, the most common and mature type of bone cell. Osteoclasts, the cells that break down and reabsorb bone, stem from monocytes and macrophages rather than osteogenic cells.. There is a continual balance between osteoblasts generating new bone and osteoclasts breaking down bone. Key Terms osteoclast: a large multinuclear cell associated with the resorption of bone osteocyte: a mature bone cell involved with the maintenance of bone osteoprogenitor: a stem cell that is the precursor of an osteoblast canaliculus: any of many small canals or ducts in bone or in some plants periosteum: a membrane surrounding a bone endosteum: a membranous vascular layer of cells which line the medullary cavity of a bone lacuna: a small opening; a small pit or depression; a small blank space; a gap or vacancy; a hiatus osteoblast: a mononucleate cell from which bone develops Key Points Compact bone is the hard external layer of all bones that protects, strengthens, and surrounds the medullary cavity filled with marrow. Cylindrical structures, called osteons, are aligned along lines of the greatest stress to the bone in order to resist bending or fracturing. Spongy or cancellous bone tissue consists of trabeculae that are arranged as rods or plates with red bone marrow in between. Spongy bone is prominent in regions where the bone is less dense and at the ends of long bones where the bone has to be more compressible due to stresses that arrive from many directions. Key Terms trabecula: a small mineralized spicule that forms a network in spongy bone epiphysis: the rounded end of any long bone osteocyte: a mature bone cell involved with the maintenance of bone osteon: any of the central canals and surrounding bony layers found in compact bone

bone healing process
inflammation, soft callous, hard callous, remodeling 1. First there is inflammation and clotting. 2. Then fibroblasts secrete matrix forming cartilage for new bone to build off if. 3. Osteoblasts will secrete new bone spindle, where osteocytes will maintain the bone. 4. Clasts will dissolving cartilage and replacing it with bone 1. Hematoma formation: Blood vessels in the broken bone tear and hemorrhage, resulting in the formation of clotted blood, or a hematoma, at the site of the break. The severed blood vessels at the broken ends of the bone are sealed by the clotting process. Bone cells deprived of nutrients begin to die. 2. Bone generation: Within days of the fracture, capillaries grow into the hematoma, while phagocytic cells begin to clear away the dead cells. Though fragments of the blood clot may remain, fibroblasts and osteoblasts enter the area and begin to reform bone. Fibroblasts produce collagen fibers that connect the broken bone ends, while osteoblasts start to form spongy bone. The repair tissue between the broken bone ends, the fibrocartilaginous callus, is composed of both hyaline and fibrocartilage. Some bone spicules may also appear at this point. 3. Bony callous formation: The fibrocartilaginous callus is converted into a bony callus of spongy bone. It takes about two months for the broken bone ends to be firmly joined together after the fracture. This is similar to the endochondral formation of bone when cartilage becomes ossified; osteoblasts, osteoclasts, and bone matrix are present. 4. Bone remodeling: The bony callus is then remodelled by osteoclasts and osteoblasts, with excess material on the exterior of the bone and within the medullary cavity being removed. Compact bone is added to create bone tissue that is similar to the original, unbroken bone. This remodeling can take many months; the bone may remain uneven for years.

Pancreas
is 6-10 inches long and located at the back of the abdomen behind the stomach. The wider right side called the Head is near duodenum, the Tail end is near spleen It is made up of endocrine and Exocrine tissue the exocrine tissue Secretes digestive enzymes from the main pancreatic ducts which connects to the common bile duct near duodenum. The endrocrine tissue secretes hormones such as insulin into the bloodstream. Blood is supplied to the pancreas via the splenic artery, gastroduodenal atery, and the superior mesenteric artery. The pancreas digestive FUNCTION is secreting enzymes which help in the breakdown of foods, but especially fats and proteins. Proteases digest proteins. Proteases secreted by the pancreas: trypsin, carboxypeptidase, and chymotrypsin. -Other pancreatic enzymes: amylase, lipase, and nucleases Regulation of Bile and Pancreatic Secretion and Entry into the Small Intestine 1. secretin - will stimulate the liver to secrete bile; it is released by the intestinal cell when they are exposed to fatty chyme a. secretin can also be released in response to HCl in the intestine; it targets pancreatic duct cells to release sodium bicarbonate. 2. cholecystokinin (CCK) - is the major stimulus that produce gall bladder contractions. CCK is secreted into the blood and also stimulates secretion of pancreatic juices and relaxes the hepatopancreatic sphincter a. meals high in proteins and fats will cause CCK to stimulate the release of enzyme rich pancreatic juices.

connective tissue proper
loose connective tissue and dense connective tissue. Connective tissue proper encompasses the types of connective tissue that usually show all three of the defining cellular characteristics of connective tissue with the fewest deviations from those characteristics. -Dispersed cells -More extracellular material than cells. -Extensive protein fibers in the extracellular matrix. Some are classified as *dense* connective tissue proper and have a dense arrangement of extracellular protein fibers that give the tissue *strength and toughness*. Tendons connecting muscles to bone and ligaments connecting bone to bone are examples of dense connective tissue proper. Other tissues are classified *loose connective tissue proper* and have fewer extracellular protein fibers and more ground substance (the extracellular material surrounding the protein fibers), making the tissues *spongier but more fragile.* Areolar tissue, found in the hypodermis of the skin and below the epithelial layers of the digestive, respiratory, and urinary tracts, is a loose connective tissue proper, as is adipose tissue, also known as fat. Tendons connect muscle to bone. Ligaments connect bone to bone.

It carries hormones and defends against disease. Lymph - the lymphatic tissue includes the lymph nodes, spleen, tonsils, adenoids and the thymus •Loose connective tissue - is the most common type of connective tissue in vertebrates. It holds organs in place and attaches epithelial tissue to other underlying tissues. •Dense connective tissue - tendons, ligaments, vocal chords, arteries ----------- Connective tissue is divided into four main categories: -Connective proper -Cartilage -Bone -Blood Connective tissue proper has two subclasses: loose and dense. -Loose connective tissue is divided into 1) areolar, 2) adipose, 3) reticular. -Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic. Areolar Connective Tissue These tissues are widely distributed and serve as a universal packing material between other tissues. The functions of areolar connective tissue include the support and binding of other tissues. It also helps in defending against infection. When a body region is inflamed, the areolar tissue in the area soaks up the excess fluid as a sponge and the affected area swells and becomes puffy, a condition called edema. Adipose Tissue or Body Fat Adipose tissue: Yellow adipose tissue in paraffin section with lipids washed out. This is loose connective tissue composed of adipocytes. It is technically composed of roughly only 80% fat. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. The two types of adipose tissue are white adipose tissue (WAT) and brown adipose tissue (BAT). Adipose tissue is found in specific locations, referred to as adipose depots. Reticular Connective Tissue This tissue resembles areolar connective tissue, but the only fibers in its matrix are the reticular fibers, which form a delicate network. The reticular tissue is limited to certain sites in the body, such as internal frameworks that can support lymph nodes, spleen, and bone marrow. Dense Regular Connective Tissue This consists of closely packed bundles of collagen fibers running in the same direction. These collagen fibers are slightly wavy and can stretch a little bit. With the tensile strength of collagen, this tissue forms tendons, aponeurosis and ligaments. This tissue forms the fascia, which is a fibrous membrane that wraps around the muscles, blood vessels, and nerves. Dense Irregular Tissue This has the same structural elements as dense regular tissue, but the bundles of collagen fibers are much thicker and arranged irregularly. This tissue is found in areas where tension is exerted from many different directions. It is part of the skin dermis area and in the joint capsules of the limbs. Elastic Connective Tissue The main fibers that form this tissue are elastic in nature. These fibers allow the tissues to recoil after stretching. This is especially seen in the arterial blood vessels and walls of the bronchial tubes. Cartilage This is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes, and the intervertebral discs. Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels. Cartilage is classified in three types: 1) elastic cartilage, 2) hyaline cartilage, and 3) fibrocartilage, which differ in the relative amounts of these three main components. Elastic Cartilage This is similar to hyaline cartilage but is more elastic in nature. Its function is to maintain the shape of the structure while allowing flexibility. It is found in the external ear (known as an auricle) and in the epiglottis. Hyaline Cartilage This is is the most abundant of all cartilage in the body. Its matrix appears transparent or glassy when viewed under a microscope. It provides strong support while providing pads for shock absorption. It is a major part of the embryonic skeleton, the costal cartilages of the ribs, and the cartilage of the nose, trachea, and larynx. Fibrocartilage This is a blend of hyaline cartilage and dense regular connective tissue. Because it is compressible and resists tension well, fibrocartilage is found where strong support and the ability to withstand heavy pressure are required. It is found in the intervertebral discs of the bony vertebrae and knee meniscus. Bone Bone tissue is also called the osseous tissue. The osseous tissue is relatively hard and lightweight in nature. It is mostly formed of calcium phosphate in the chemical arrangement termed calcium hydroxyapatite, which gives bones their rigidity. It has relatively high compressive strength, but poor tensile strength, and very low shear stress strength. The hard outer layer of bones is composed of compact bone tissue, so-called due to its minimal gaps and spaces. Its porosity is 5-30%. This tissue gives bones their smooth, white, and solid appearance, and accounts for 80% of the total bone mass of an adult skeleton. Filling the interior of the bone is the trabecular bone tissue (an open cell porous network also called cancellous or spongy bone), which is composed of a network of rod and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow. Blood This is considered a specialized form of connective tissue. Blood is a bodily fluid in animals that delivers necessary substances, such as nutrients and oxygen, to the cells and transports metabolic waste products away from those same cells. It is an atypical connective tissue since it does not bind, connect, or network with any body cells. It is made up of blood cells and is surrounded by a nonliving fluid called plasma.
