Quizplus · Accepted Answer

Skin vasoconstriction is the major means of decreasing heat loss in response to a cold environmental temperature. This is because vasoconstriction reduces blood flow to the skin and subcutaneous tissues, thereby reducing the temperature gradient between the skin and the environment and minimizing heat loss.
