Chapter 1, Problem 9CP
Summary Introduction
To review:
The types of disturbances that can act as stimuli that initiate a feedback system.
Introduction:
A feedback system is formed by communication of group of receptors and effectors with their respective control center, which in turn, regulate a controlled condition in the body's internal environment.
