A system that is prevalent throughout several organisms, homeostasis maintains a stable, constant internal environment, despite external, environmental variations. Such a function, operates through a series of feedback controls, in attempt to preserve the equilibrium in the internal environment. In control of these feedback mechanisms, are the nervous system and the endocrine system. Furthermore, homeostasis will often involve balancing blood pressure, respiration, temperature (such as shivering as a response to chilly temperatures, like pictured above), electrolyte balance, pH balance, water balance, and much more. As can be seen, homeostasis is quite necessary to a plethora of organism’s struggles, when combating the fierce and unforgiving world.
