P5/M2 - Homeostasis
Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in an effort to maintain an internal temperature at around 37®C. For example, during the summer when the weather is very hot (outside condition) we sweat to cool ourselves down and in the winter when the weather is very cold (outside condition) we shiver to help our bodies to produce heat to keep ourselves warm. Key facts

Homeostasis is the body's attempt to maintain a constant and balanced internal environment, which requires persistent monitoring and adjustments as conditions change. Homeostatic regulation is monitored and adjusted by the receptor, the command centre, and the effector. The receptor receives information based on the internal environment; the command centre, receives and processes the information; and the effector responds to the command centre, opposing or enhancing the stimulus. (Boundless, 2013)

Living cells can function only within a narrow range of such conditions as temperature, pH , ion concentrations, and nutrient availability, yet living organisms must survive in an environment where these and other conditions vary from hour to hour, day to day, and season to season. Organisms therefore require mechanisms for maintaining internal stability in spite of environmental change. American physiologist Walter Cannon (1871–1945) named this ability homeostasis ( homeo means "the same" and stasis means "standing or staying"). Homeostasis has become one of the most important concepts of physiology, physiological ecology, and medicine. Most bodily functions...
