Question

Quizplus · Accepted Answer

Lying in the shade is a behavioral response and not a physiological response of the mammalian thermoregulatory system. Physiological responses involve changes in the body's internal processes, such as increasing thyroid activity to increase metabolic rate, constricting cutaneous blood vessels to conserve heat, or sweating to release heat through evaporation. Lying in the shade is a behavioral response that removes the animal from direct sunlight and reduces heat gain, but it does not involve any internal processes.
