Human-Anatomy 1.3
The body's organ systems and their major functions
| Question | Answer |
|---|---|
| integumentary | forms the external covering, and protects deeper tissues from injury. Dynthesizes vitimin D, and houses cutaneous (pain, pressure, ect.) receptors and sweat and oil glands. |
| skeletal | protects and supports body organs, and provides framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals. |
| muscular | allows manipulation of the enviroment, locomotion, and facial expression, maintains posture and produces heat. |
| nervous | as the fast acting control system of the body, it responds to internal and external changes by activating appropriate musles and glands, muscle contraction or gland secretion. |
| endocrine | glands secrete hormones that regulate processes such as growth, reproduction and nutrient use (metabolism) by body cells |
| cardiovascular | blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood. |
| lymphatic | (immunity)picks up fliid leaked from blood vessels and returns it to blood. Disposes or debris in the lymphatic stream, houses white blood cells (lymphocytes)involved in immunity. |
| respiratory | keeps blood constantly supplied with oxygen and removes carbon dioxide. The faseous exchanges occur through the walls of the air sacs of the lungs. |
| digestive | breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible food stuffs are eliminated as feces. |
| urinary | eliminates hitrogenous wastes from the body. Regulates water, electrolyte and acid base balance of the blood. |
| reproductive | overall function is production of offspring |
