Quizplus · Accepted Answer

When in a warm environment, the body needs to lose heat to maintain homeostasis. Arterioles are small blood vessels that regulate blood flow in the dermis. Dilating them allows more blood to flow to the surface of the skin, allowing for greater heat loss through radiation and convection. Therefore, in response to a warm environment, the arterioles in the dermis will dilate to lose heat.
