feedback mechanism

feed·back mech·an·ism

/ˈfēdˌbak ˈmekəˌnizəm/

Noun

If the body senses that something is happening that takes it out of homeostasis, it will perform an action that brings it back into balance. These actions take the form of Feedback Mechanisms. Negative Feedback Mechanisms attempt to bring the body back into homeostasis (like shivering in the cold in order to create heat), while Positive Feedback Mechanisms purposefully take the body out of homeostasis temporarily for a specific purpose (like raising the body temperature in order to kill a viral infection).
