Summary Introduction
Introduction:
Feedback systems are part of control systems in the body. These are present in almost all living organisms. There are different types of feedback systems that are used to control a particular process or change taking place in the body. Depending on whether the control system increases or decreases an effect, feedback control systems can be classified as negative feedback and positive feedback control system.
