Document Summary

Homeostasis - all kinds, same state, ability of body to protect body from environmental change by changing internal environment within a physiological range. Defined as maintenance of a relatively stable internal environment o. Does not mean that composition, temperature, and other characteristics are absolutely unchanging o. The body is in a constant state of dynamic equilibrium. Homeostasis is essential for survival and function of all cells. Each cell contributes to maintenance of a relatively stable internal environment. In order to maintain homeostasis, control system must be able to o. Detect deviations from normal in the internal environment that need to be held within narrow limits o o. Integrate this information with other relevant information to make decisions. Make appropriate adjustments in order to restore factor to its desired value. Homeostatic control systems: negative feedback system o o o o. Makes a response to produce a desired effect.
