Homeostasis: Thermoregulation

Homeostasis is the ability to maintain balance in the body even in fluctuating external conditions. In order for the body to keep this constant internal state it must be able to recognise and detect changes in the external environment, these changes are referred to as stimuli as they are what stimulate the change in internal conditions. The body detects these changes with receptors which communicate signals to the hypothalamus in the brain which is the control centre for this homeostatic system. The hypothalamus responds to these signals by causing an effector to bring about an appropriate response which will keep the internal environment of an organism constant in the changing external environment. An example of homeostasis is thermoregulation. Thermoregulation is the system in which organisms maintain a constant internal body temperature in a constantly changing external temperature. It is important for our bodies to maintain conditions within tolerable limits to ensure the human body functions healthily.
This means that thermoregulation was an important part of keeping their bodies functioning healthily. Thermoregulation is a negative feedback system. This means that the system is one in which the body experiences to return the desired state to maintain the stability. The human body functions at its best when the internal temperature is 37°C. Although, our bodies are still able to function at temperatures between 35°C and 40°C. Therefore thermoregulation works to maintain this temperature internally when the external temperature is lower or higher than
