MICROANATOMY

Detailed explanation-1: -The blood vessels of the dermis provide nutrients to the skin and help regulate body temperature. Heat makes the blood vessels enlarge (dilate), allowing large amounts of blood to circulate near the skin surface, where the heat can be released. Cold makes the blood vessels narrow (constrict), retaining the body’s heat.

Detailed explanation-2: -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.

Detailed explanation-3: -The dermis also contains pain and touch receptors. The subcutaneous fat layer is the deepest layer of skin. It consists of a network of collagen and fat cells. It helps conserve the body’s heat and protects the body from injury by acting as a shock absorber.
