Homeostasis refers to the processes of keeping internal body environment in a steady rate‚ when the external environment is changed. The aim of this essay is to discuss the internal environment‚ the importance of regulation of core temperature‚ negative feedback and positive feedback and contrast control of core body temperature in normal conditions and in hypothermia. The internal environment of living organisms is enclosed within the body. It features body fluids in multicellular animals (includes
