The four components of homeostasis are a change, a receptor, a control center and an effector. Stimulus produce change in variable (body temperature falls), Receptor detect change (detected by thermoreceptors in skin). For instance, when there is a hemorrhage (loss of blood), it will cause a sequential activation of clotting factors. This creates a situation of "metastability," in which homeostatic conditions are maintained within fixed limits, but once these limits are Homeostatic feelings operate within the compass of basic homeostasis. An example is the body regulating its internal temperature by shivering or sweating. All homeostatic control mechanisms have at least three interdependent components for the variable being regulated: a receptor, a control centre, and an effector. Using the same example, the medulla oblongata commands the effector -- the heart in this case -- to slow its pulse. Direct link to Ltnt.
