Explanation;
-Feedback system is a cycle of events in which a body condition is monitored, evaluated, change,re monitored, reevaluated, etc.
-Feedback systems contain three basic components, receptor, control center and effector. A group of receptors and effectors communicating with their control center forms a feedback system that can regulate a controlled condition in the body.
-A receptor is the body structure that monitors changes in a controlled condition and sends input to a control center. The effector receives output from the control center and produces a response or effect that changes the controlled condition.
