The heat generated by the core body tissues travels to the vasodilated skin surface capillaries, and the temperature gradient between the limbs and environment drives transfer of heat to the surrounding air, mainly by radiation. WebIn response to cold, many warm-blooded animals also reduce blood flow to the skin by vasoconstriction to reduce heat loss. As a result, they blanch (become paler). Avoiding overheating.
