A properly functioning homeostatic control system is seen when, for example, a person’s body temperature remains relatively constant despite changes in the external environment. This stability is achieved by negative feedback loops where the input signal of change causes an output response that opposes it (e.g., shivering to produce more heat and sweating to cool off).
– In the body, this is accomplished by a hypothalamus which continuously monitors and adjusts various hormones that maintain homeostasis. In other words: The properly functioning homeostatic control system maintains stability through negative feedback loops where input signals cause output responses to oppose them.
For example, if someone’s temperature changes as they move from one environment into another with different heat or humidity levels, their body may produce more sweat (to cool off) or shiver (to generate warmth). These actions are regulated by an area of the brain called the hypothalamus which either releases hormones for increased production of these reactions in response to external stimuli changing those factors; or it suppresses hormone release when there has been no change in environmental conditions.
