When cold, the skeletal muscles will be activated to generate more heat by and blood vessels constrict to keep the blood warm, and blood is diverted from the skin capillaries and is withdrawn to deep tissues. When the body is hot, sweat glands are activated to secrete sweat which allows the body to cool down. The skin blood vessels will dilate, the capillaries will become flush with allowing heat to radiate from the skin surface.
