Question

Quizplus · Accepted Answer

Arterioles are small muscular blood vessels that regulate blood flow to the capillaries. When they constrict, it reduces blood flow to the skin, which decreases heat loss and causes the skin to appear pale. Veins, capillaries, and venules are not involved in this process. Arteries may also constrict in response to fear or cold, but they are not present in the skin.
