Document Summary

List the levels of organization in the human body. The fluid in which our cells are bathed; essentially interstitial fluid and blood. Region outside the body, including space and contents of digestive, Contain the following: a set point, a control center (integrator, an effector, a controlled variable, a sensor (receptor) A self-amplifying mechanism where the controlled variable actually stimulates its own production: controlled variable is detected by the, sensor signals the control center, control center activates the effector, effectors produce more of the control sensor variable. The study of function in living organisms, how an organism maintains homeostasis, and explains physical and chemical factors responsible for both normal function and disease. The maintenance of relatively stable conditions within the internal environment regardless of what is happening in the external environment through negative and positive feedback control. Maintains homeostasis by always returning to the set point.
