Which is an adaptation to manage cold in extremities?

Question

Quizplus · Accepted Answer

Blood shunting is an adaptation that diverts blood away from extremities to the core of the body. This helps to conserve heat and maintain core body temperature. Concurrent circulation refers to the flow of blood in opposite directions in adjacent blood vessels and is not a direct adaptation to manage cold in extremities. Lack of precapillary sphincters would lead to an inability to regulate blood flow to specific areas of the body, which would not be an effective adaptation for managing cold in extremities. Increased insulation is a general adaptation to cold and may not specifically target extremities.
