Endocrine System
9A student walks home one day and encounters a mean, barking dog. The student becomes scared and runs away from the dog. This fight or flight respons is induced by the:
Endocrine System
Hormones generated by glands within the brain, and other parts of the body are produced by what system?
Endocrine System
This system is significant because it maintains homeostasis in the body.
Endocrine System
The body system which filters water and wastes from the blood is the:
Excretory System
This system rids the body of cellular wastes.
Excretory System
Excretory System
Filters, collects, and removes excess fluids and wastes from the bloostream; includes kidneys and bladder
Nervous System
Funtions as the control center, coordinating all actions and reactions; includes brain, spinal cord, and nerves
Skeletal System
Holds organs in place, provides structural support, stores minerals, and generates new blood cells; includes the bones and joints
8What is the correct order of the processes listed below that explain how food is processed through the digestive system? I. The food travels down the esophagus into the stomach. II. The digested food travels through the intestines and is excreted out the body. III. The stomach uses acids to chemically break down the food. IV. Salivary glands produce saliva that combines with teeth to further break down food into smaller components.
IV, I, III, II
15A student begins to run a fever and is feeling sick. Which body system responds by fighting off sickness through production of white blood cells?
Immune system
One body system works with the immune system to protect the body against foreign invaders, with the skin as the first barrier in that system through which substances must penetrate to enter the body.
Integumentary System
Reproductive System
Male and female systems used to produce offspring; Females have a uterus and ovaries, and males have a penis and testicles.
17The muscle system allows:
Movement
Muscles are a part of what system?
Muscular System
This system includes the brain, spinal cord, and all the nerves; it is the system that controls most of the other systems.
Nervous System
Immune System
Protects body by fighting sickness and disease, such as caused by viruses and bacteria; includes lymph nodes, tonsils, and spleen.
6The main function of the circulatory system is to:
Pump oxygen and nutrients through the bood to every part of the body.
Integumentary System
Reacts to external environmental conditions and protects the body's deeper tissues; Includes skin, hair, nails, and sweat glands.
Endocrine System
Regulates body by secreting hormones into the bloodstream; also controls growth, reproduction, and metabolism; includes glands and hormones
In order for genetic information to be passed from parents to offspring, this system is necessary.
Reproductive System
What system works in conjunction with the circulatory system, by providing it with the oxygen that is needed by the body?
Respiratory System
What systems provides the body with a rigid support system that includes the bones.
Skeletal System
Homeostasis is the body's process of maintaining what 2 things?
Stability and balance
The function of the respiratory system is to:
Supply blood with oxygen and remove carbon dioxide in the lungs.
Biceps flexing while lifting weights
Support and protect delicate organs such as the brain, lungs, and heart.
3Skin is filled with many nerves so that the body can detect pain, sensation, pressure and temperature. If the body gets too warm, then the integumentary system responds by having:
Sweat gland secrete sweat to cool the skin's surface.
True or False: The nervous system allows you to feel the heat from the hot pan?
TRUE
Describe the function of all ten body systems, the organs associated with each body system, and how the body systems interact with each other.
The circulatory system circulates blood through the body, supplies cells with oxygen and nutrients and removes waste products. Organs: heart, arteries, veins. The immune system responds to pathogens and provides defenses to the body's systems from disease. Organs: lymph nodes, tonsils, spleen. The respiratory system supplies blood with oxygen in the lungs and removes carbon dioxide. Organs: larynx, trachea, bronchial tubes, lungs, alveoli. The skeletal system holds organs in place, provides a structural support for the body and its muscles, stores minerals and contains materials to make new blood cells. Organs: bones, joints. The muscular system allows the body to move when attached to bone, and allows movement in internal organs such as the heart and intestines. Organs: muscles, ligaments, tendons. The digestive system converts food into simpler substances for the body to absorb as nutrients. Breakdown of food also provides energy for all body functions. Organs: teeth, esophagus, stomach, small intestine, large intestine, anus. The excretory system filters water and fluids from the blood while also collecting waste urine. Organs: kidneys, bladder. The integumentary system continuously receives communication with the external environment (temperature, humidity, etc.) and protects the body's deeper tissues. It excretes waste, helps rid the body of heat and synthesizes vitamin D. Organs: skin, hair, nails, sweat glands. The nervous system sends immediate and specific information as electrical impulses. Organs: brain, spinal cord, nerves. The endocrine system sends signals in the form of hormones to the body. The endocrine system controls growth, reproduction and metabolism. Organs: glands, hormones. Example of systems interacting: The nervous and endocrine systems work together and are the body's two systems for control and communication.
Describe the function of the endocrine system and the "fight or flight" response.
The endocrine system regulates the body by secreting different types of hormones into the bloodstream. Hormones are chemical messengers that help regulate body functions such as mood, growth, development, tissue functions, and metabolism. When a person is scared, a hormone called adrenaline is released into the bloodstream. This hormone speeds heart and breathing rates to transport more oxygen to the muscles. The response allows a person to "fight" if their opponent is small or the person feels they can defeat it; or "flight"/run away if the opponent is too big or thought to be a threat.
How do the heart and lungs work together to provide oxygen to all cells in the body?
The lungs supply oxygen to the blood. The heart delivers the blood throughout the body.
How do the heart and lungs work together to provide oxygen to cells?
The lungs supply oxygen to the blood. The heart delivers the blood throughout the body.
