Homeostasis and the Maintenance of Integrity

Abstract

Organisms exist as complex, relatively stable physical and chemical systems, despite the permanent wear and degradation of particular elements. Such stability is manifested through various factors including the permanency of their molecular composition, acidity, temperature, pressure, and so on. The ability of an organism to maintain its integrity secures its survival and prolonged existence under variable conditions. All organisms developed anatomic, physiological, biochemical, and behavioral adaptations that serve one purpose: to preserve the constancy of the internal environment in order to provide optimal conditions for vital activities and reproduction. Organisms are able to maintain and regulate all structural and functional parameters (within certain narrow limits) for quite long periods of time, a necessary condition for uninhibited life.
