| Question | Answer |
|---|---|
| integumentary | MAJOR COMPONENT ORGANS: epidermal and dermal regions; cutaneous sense organs and glands FUNCTION: - protects deeper organs from mechanical, chemical, and bacterial injury, and desiccation (dryiing out) - excretes salts and urea - body temperature reg. |
| skeletal | ORGANS: bones, cartilages, tendons, ligaments, and joints FUNCTION: - body support and protection of internal organs - provides levers for muscular action - cavities provide a site for blood cell formation |
| muscular | ORGANS: muscles attached to the skeleton FUNCTION: - primary function is to contract or shorten - allow locomotion (running, walking, etc.) - generates heat - |
| nervous | ORGANS: brain, spinal cord, nerves, and sensory receptors FUNCTIONS: - allows body to detect changes in its internal and external environment and to respond to such information by activating app. muscles or glands - helps maintain homeostasis of the bo |
| endocrine | ORGANS: pituitary, thymus, thyroid, parathyroid, adrenal, pineal glands: ovaries, testes, pancreas FUNCTIONS: maintain body homeostasis, promotes growth and dev., chemical hormones that travel in the blood to exert their effects on "target organs" |
| cardiovascular | ORGANS: heart, blood vessels, blood FUNCTIONS: transport system that carries blood containing oxygen, co2, nutrients, wastes, ions, hormones, and other substances to and from the tissue cells where exchanges are made, pumping action of heart for blood |
| lymphatic/immunity | ORGANS: lymphatic vessels, lymph nodes, spleen, thymus, tonsils, scattered collection of lymphoid tissues FUNCTIONS:cleanses blood of pathogens and other debris, houses lymphocytes that act as via the immune response to protect body from foreign stuff |
| respiratory | ORGANS: nasal passages, pharynx, larynx, trachea, bronchi, lungs FUNCTIONS: keeps the blood continuously supplied with oxygen while removing carbon dioxide |
| digestive | ORGANS: oral cavity, esophagus, stomach, small and large intestines, accessory structures (teeth, salivary glands, liver, pancreas) FUNCTIONS:breaks down ingested foods to minute particle, undigested residue removed from the body as feces |
| urinary | ORGANS: kidneys, ureters, bladder, urethra FUNCTIONS: rids the body of nitrogen-containing wastes which result from the breakdown of proteins and nucleic acids by body cells, maintains water, electrolyte, and acid-base balance of blood |
| reproductive | ORGANS: testes, prostate gland, scrotum, penis, duct system, ovaries, uterine tubes, uterus, mammary glands, vagina FUNCTIONS: males: provides germ cells (sperm_ for perpetuation of the species, (females): eggs, fetus in uterus, mammary provide nutrition |
