Organ Systems - ch 5 Flashcards
Integumentary System
- skin
- protection (primary function)
- regulates body temperature & synthesizes chemicals
- sense organ
- 20 lbs. (16% of body weight)
Skeletal System
- bones, ligaments, cartilage, joints & tendons
- supporting framework for body
- movement
- storage of minerals
- formation of blood cells
Nervous System
- communication between body organs
- integration & control of body functions
- recognition of sensory stimuli
Cardiovascular System
- heart, arteries, veins & capillaries
- transportation of substances throughout the body
- regulation of body temperature
- immunity
Immune System
- phagocytes, secretory cells & protein compounds
- phagocytosis of bacteria, chemical reactions that provide protection from harmful agents
Respiratory System
- nose, pharynx, larynx, trachea, bronchi & lungs
- exchange of carbon dioxide for oxygen in the alveoli
- filters irritants from inspired air
- regulation of acid/base balance
Muscular System
- primary organs are muscles
- function is movement
Endocrine System
- glands, pancreas, ovaries & testes
- same function as nervous system, but much slower & longer duration
Lymphatic System
- lymph nodes & tonsils, thymus & spleen
- transportation of lymph
- immunity
Digestive System
- form alimentary canal (GI tract)
- mechanical & chemical breakdown of food
- absorption of nutrients
- elimination of undigested waste
Urinary System
- kidneys, ureters, bladder & urethra
- “clearing” of waste products
- electrolyte balance
- water balance
- acid/base balance
Reproductive System
- survival of genes
- transfer & fertilization of sex cells
- development, birth, & nourishment of offspring
- skin
- protection (primary function)
- regulates body temperature & synthesizes chemicals
- sense organ
