The body maintains homeostasis by utilizing homeostatic control systems composed of three parts. the first part, the ___RECEPTOR_ , is the body structure that detects changes in a variable that is either the substance or process that is regulated. these usually consist of ___SENSORY NERVES__ . the change in the variable is the ___STIMULUS__ . The second component is the __CONTROL CENTER__ . It is the structure that interprets input from the receptor and initiates changes through the __EFFECTOR_ (the final component). this final component is the structure that brings about the change to alter the __STIMULUS_ .
