The skin is the most sensitive organ in our body which responds to touch, temperature etc.
Skin is the largest organ of our body. It acquires an area of around 20 square feet in our body. It is the most vital organ in our body. It consists of a large fleshy surface with nails, hairs, glands and nerves. The skin also contains the hair follicles through which the hair anchors.
The texture of the skin is different at different areas. For example skin at the heels and palms are thicker as compared to others. The function of skin is that it acts as a barrier which protects the inside environment from outside. The skin contains receptors for touch, pain, temperature etc.

• . 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.
