what is negative feedback in homeostasis

Negative feedback is a mechanism used by the body to maintain homeostasis, which is the maintenance of a relatively stable internal environment. In a negative feedback loop, feedback serves to reduce an excessive response and keep a variable within the normal range/10%3A_Introduction_to_the_Human_Body/10.7%3A_Homeostasis_and_Feedback). The hallmark of a negative feedback loop is that it counteracts a change, bringing the value of a parameter back towards its set point. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point of 98.6°F. Negative feedback is a vital control mechanism for the body’s homeostasis. Most biological feedback systems are negative feedback systems.
