Document Summary
Homeostasis keeping the body in a survivable range (86 degrees fahrenheit to. 108 degrees fahrenheit) involves maintaining an equilibrium between processes that heat and cool the body up and down: homeostatic mechanisms mechanisms that keep the body in the homeostasis state of equilibrium. Endocrine system: assists the nervous system in maintaining homeostasis, and commanding/controlling the body, made up of glands. Oppose the action of other hormones: information processing system that runs parallel to the nervous system. Constriction of surface blood vessels warm blood is kept away from the cold skin surface, blood is relatively warm as it flows back to the body"s core. Raising of small body hairs create a buffer of relatively still air over the skin"s surface, acting as insulation. Shivering form of activity that warms the body by increasing the metabolism, more efficient than other forms of activity because it doesn"t increase the flow of air over the body.
