The skin and its derivatives hair, nails, sweat and oil glands make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature. The skin contains secretions that can kill bacteria and the pigment melanin provides a chemical pigment defense against ultraviolet light that can damage skin cells. Another important function of the skin is body temperature regulation. When the skin is exposed to a cold temperature, the blood vessels in the dermis constrict. This allows the blood which is warm, to bypass the skin. The skin then becomes the temperature of the cold it is exposed to. Body heat is conserved since the blood vessels are not diverting heat to the skin anymore. Among its many functions the skin is an incredible organ always protecting the body from external agents.

Skin. Anatomy of the Skin

The Skin is the largest organ of the human body. It is soft, to allow movement, but still tough enough to resist breaking or tearing. It varies in texture and thickness from one part of the body to the next, Skin. For instance, Skin, the skin on our lips and eyelids is very thin and delicate, while skin on the soles of our feet is thicker and harder. Our skin is a good indicator of our Skin health. If someone is sick, it often shows in their skin. The skin you can see is called the epidermis, Skin. This protects the Skin delicate inner layers. The bottom sheet is where new epidermal cells are made, Skin. As old, dead skin cells are sloughed off the surface, new ones are pushed up to replace them, Skin. The epidermis also contains melanin, the pigment that gives skin its colour. Under Skin epidermis is the dermis. This is made up Skin elastic fibres elastin for suppleness and protein fibres collagen for strength. The dermis contains sweat glands, Skin, sebaceous glands, hair follicles, blood vessels and nerves. The subcutis is a layer of fat that sits immediately under the dermis.
