Summary Introduction
To review:
The definition of “negative feedback.”
Introduction:
Homeostasis is the process of the body to maintain a constant stable internal condition even when the continuous external environment is changing. The homeostasis in the body is constantly being regulated by various positive and negative feedback mechanisms. Generally, the negative feedback mechanisms control the homeostatic mechanisms. In these systems, the net effect of the response is either reduced or shut off.
