MICROANATOMY

Detailed explanation-1: -Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level.

Detailed explanation-2: -Body temperature control is a negative feedback system that occurs in the body. If the body temperature rises or falls, the response of shivering or sweating will reverse the change that has occurred.

Detailed explanation-3: -Feedback loops are created when reactions affect themselves and can be positive or negative. Consider a thermostat regulating room temperature. This is an example of a negative feedback loop. As the temperature rises, the thermostat turns off the furnace allowing the room to rest at a predetermined temperature.

Detailed explanation-4: -If the temperature is high, the body sweats in order to cool down. Since the process of sweating is done to stop the temperature change, this is a negative feedback. Feedback loops come in two flavors: positive and negative. A negative feedback loop reduces the effect of change and helps maintain balance.

Detailed explanation-5: -In a positive feedback loop, feedback serves to intensify a response until an endpoint is reached. Examples of processes controlled by positive feedback in the human body include blood clotting and childbirth.
