Integumentary System • • • The Integumentary system has multiple roles in homeostasis, including protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. The Integumentary system is also responsible for hair, scales, feathers, claws, horns, and nails. Hot and cold receptors are located in the skin. When body temp rises the hypothalamus sends a nerve signal to release 1 -2 liters of water per hour. The hypothalamus also causes dilation of the blood vessels of the skin, allowing more blood to flow into those areas. In hot weather up to 4 liters per hr can be lost. Skin damaged by burns is less effective at preventing fluid loss, often resulting in a possibly life threatening problem if not treated.
Nervous system • The nervous system is a network of specialized cells that communicate about an organism’s surrounding itself.
Skeletal System • • • Provides the shape and form for our bodies in addition to supporting, protecting, allowing bodily movement, producing blood for the body, and storing minerals. Muscles which cause movement of a joint are connected to two different bones and contract to pull them together. i. e. the contraction of the biceps and a relaxation of the triceps. This produces a bend at the elbow. Blood cells are produced by the marrow located in some bones. An average of 2. 6 million blood cells are produced to replace the ones that are worn out.
Reproductive • Reproduction is the biological process by which new individual organisms are produced.
Circulatory system • • The circulatory system transports blood and oxygen from all parts of the body.
Digestive • The digestive system is made up of the digestive tract– a series of hollow organs joined together in a long, twisting tube from the mouth to the anus– and the other organs that help the break down and absorb food.
