When body temperature increases during exercise, the body response is to stimulate the sweat glands to release swat, which releases heat and brings the body temperature back to set point. In the previous description of a negative feedback mechanism to keep body temperature within homeostatic values, identify: a. the parameter that is kept constant. b. The stimulus that initiates the feedback mechanism. c. the control center d. The effector organ(s) that execute the feedback mechanism e. The final effect that results from the activation of the feedback mechanism. 6. List 1 positive feedback mechanism that are physiologically good in the human body and explain: a. why is it a positive feedback mechanism b. why is it physiologically good for the body.
