Negative Feedback System Definition

1. A type of feedback in which the system reacts to a perturbation by moving in the opposite direction to the disruption.

2. A feedback mechanism that causes a process to be inhibited or slowed down.

What is Negative Feedback System?

A feedback mechanism is a closed-loop system that responds to a disturbance. The response is also in the same direction (as in positive feedback) or in the other way (as in negative feedback).

A negative feedback reacts to a disturbance in the opposite direction to the perturbation, as opposed to a positive feedback that reacts in the same way as the perturbation. Negative feedback has a mechanism that inhibits or slows down a process, whereas positive feedback has a mechanism that initiates or accelerates it.

A negative feedback system is a self-regulatory system that feeds back to the input a portion of a system’s output in order to reverse the output’s direction of change. To stabilize or re-establish internal balance, the procedure decreases the output of a system.

Negative feedback is used to control and maintain homeostasis in biological systems. Hormone production, blood glucose levels, body temperature, and baroflex blood pressure are only a few of them.
