Integumentary System
hair, skin, nails, sweat glands (functions to protect body from damage, control body
temperature, impede loss of water, assist in production of vitamin D).
Skeletal System
bones, related cartilage, joints, ligaments (framework of the body; lends support, protection,
creates blood cells, permits movement, and provides storage for fat and minerals).
Muscular System
muscles and tendons (facilitate movement, generate body heat, and sustain posture).
Lymphatic System
lymph nodes, lymphatic vessels, various organs (eliminates foreign materials from
circulation, fight illness, regulate tissue fluid level, absorbs fatty acids contained in the
digestive tract).
Respiratory System
lungs, airways, respiratory muscles (exchanges molecules of carbon dioxide and oxygen
between the external environment and the blood. Also maintains blood pH).
Digestive System
mouth, esophagus, stomach, intestines, and various organs (mechanical and chemical
digestion of food, absorbing nutrients, and expelling waste products from the body).
Nervous System
,brain, spinal cord, nerves, sensory receptors (sensory perception, exercising control over
body movement, cognitive reasoning, and vast array of physiological processes).
Endocrine System
pituitary gland, thyroid gland, pancreas, and glands (release of hormones; influences growth
and development, metabolism, reproduction, and other physiological processes).
Cardiovascular System
heart, blood vessels, blood (utilizes blood as vehicle; distributes gases, nutrients, hormones,
and waste products. Also helps with immune response and body temperature maintenance).
Urinary System
kidneys, urinary bladder, ureters, and urethra (maintain blood pH, regulate water balance,
expel waste products from blood).
Reproductive System
The female system includes ovaries, uterus, mammary glands, vagina, and other structures
(produces oocytes, provides location for fertilization and fetal development. Also produces
hormones which facilitate lactation and sexual behaviors and functions). The male system
includes the penis, testes, various other structures (production of sperm cells and hormones
which facilitate sexual behaviors and functions).
