During exercise, one generates excess heat and the body temperature rises. As a response, blood vessels dilate in the skin, warm blood flows closer to the body surface, and heat is lost. This is an example of ________.

Question

Quizplus · Accepted Answer

This is an example of negative feedback because the body responds to an increase in temperature by initiating mechanisms (such as dilating blood vessels and increasing blood flow to the skin) to decrease the temperature and return the body to its set point or normal state. Negative feedback mechanisms work to reverse a direction of change, helping to maintain homeostasis.
