Heat loss by the skin is controlled by a positive feedback loop.

Question

Quizplus · Accepted Answer

Heat loss by the skin is actually controlled by a negative feedback loop. When the body temperature drops below a set point, the thermoreceptors in the skin send signals to the hypothalamus in the brain, which initiates responses to increase heat production and decrease heat loss, such as shivering and constricting blood vessels in the skin. Once the body temperature returns to the set point, these responses are inhibited, creating a negative feedback loop. Positive feedback loops amplify a response rather than inhibit it.
