Whether sweating is positive or negative feedback.
Introduction:
Physiology is the study of the different biological and biochemical processes that take place inside the body of a living organism and helps to regulate the functioning of the body. The feedback mechanism is used to regulate the different physiological processes taking place inside the body. There are two types of feedback systems, the negative and the positive feedback.
