Nervous System Organs:

Brain, spinal cord, nerves, sense organs

Digestive System Functions:

Break down food molecules, materials not absorbed are eliminated, some organs produce hormones

Nervous System Functions:

Communicate with each other and muscles, detect changes inside and outside the body, interpret and respond to information, stimulates muscles to contract or secrete products

Respiratory System Functions:

Exchanges gases between the blood and air

Cardiovascular System Organs:

Heart, arteries, veins, capillaries, and blood

Endocrine System Organs:

Hypothalamus, pituitary, thyroid, parathyroid, adrenal glands, pancreas, ovaries, testes, pineal gland, and thymus

Kidneys, ureters, urinary bladder, and urethra

Lymphatic System Organs:

Lymphatic vessels, lymph nodes, thymus, spleen, lymph

Reproductive System Functions:

Male: Produce and maintain sperm cells, transports sperm cells to female system Female: Produce and maintain egg cells, receives sperm cells, supports development of embryos

Reproductive System Organs:

Muscular System Organs:

Muscles

Respiratory System Organs:

Nasal cavity, pharynx, larynx, trachea, bronchi, and lungs

Homeostasis Process

Normal Temp; stimulus (change in external or internal environment); receptors (detect change); control center (receive information, then send info to muscles/organs); effectors (work to return body to previous state)

Pleural membrane lines the _________

Pleural cavity

Integumentary System Functions:

Protect underlying tissues, help regulate body temperature, house a variety sensory receptors, and synthesizes certain products

Skeletal System Functions:

Provide frameworks and protective shields for softer tissues, attachments for muscles; tissues within bones also produce blood cells and store inorganic salts

Muscular System Functions:

Provides movement and forces that moves body parts, maintains posture, major source of heat

Urinary System Functions:

Removes waste from blood, maintains the body's water and electrolyte concentrations (urine is a by-product), stores and transports urine out of the body

Abdominal Regions

Right hypochondriac, epigastric, left hypochondriac, right lateral, umbilical, left lateral, right inguinal, pubic, left inguinal
