ExplanationThe term homeostasis describes the maintenance of nearly constant conditions in the internal environment of the body, and diseases are generally considered to be states of disrupted homeostasis. However, even in diseases, homeostatic compensatory mechanisms continue to operate in an attempt sustain body functions at levels that permit life to continue. These compensations may result in deviations from the normal level of some body functions as a “trade-off” that is necessary to maintain vital functions of the body.
