Detailed explanation-1: -When the sweat evaporates from the skin surface, the body is cooled as body heat is dissipated. In addition to sweating, arterioles in the dermis dilate so that excess heat carried by the blood can dissipate through the skin and into the surrounding environment (Figure 2b).

Detailed explanation-2: -Glands are found throughout your skin. They release materials like water, salt or oil from under your skin to the surface of your skin. Your integumentary system consists of the following glands: Sudoriferous glands: These are the glands that secrete sweat through your skin.

Detailed explanation-3: -Sweat glands in the skin allow the skin surface to cool when the body gets overheated. Thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin. Immune cells present among the skin layers patrol the areas to keep them free of foreign materials.

Detailed explanation-4: -Your skin regulates your body temperature through blood vessels and through the process of sweating. The skin is in effect your body’s thermostat. When you’re out in cold weather, your skin triggers shivering so the blood vessels will contract and keep you as warm as possible.
