Question: How do negative feedback mechanisms contribute to homeostasis?

Response: Negative feedback systems tend to maintain conditions that require frequent monitoring and adjusting within physiological limits, so as to maintain homeostasis. Changes that occur in a "controlled condition" are monitored by receptors. These receptors feed back information to the "control center." If the response of the "control center" reverses the original stimulus, then the system is a negative feedback loop. On the other hand, if the response enhances the original stimulus, then the system is a positive feedback loop.

Therefore, negative feedback mechanisms help ...
