Homeostasis Homeostasis is the process which maintains a constant internal body environment. The process relies on the mechanisms which keep this internal environment within very narrow limits, despite fluctuating external conditions. This is achieved by a process called negative feedback to maintain the set point. Whenever a change occurs in a system, receptors detect the change and activate the effectors, which automatically cause a corrective mechanism to start. This brings about changes of a factor to restore the system back to normal. The bigger the change of a factor from its set point, the larger the corrective mechanism. However an efficient homeostatic system minimises the size of the fluctuations about the set point. This process ensures that cells within the internal environment of an organism are constantly surrounded by a fluid with temperature, pH and water potential which is relatively constant despite changes which try to alter them. This is...
