Trending body is the biggest finger? Do you know that most of the body is our outer layer, that is, the skin. Let us understand in detail.

There are three main skin. Epidermis is at the top. The bottom of this is called the dermis and the inner layer is called hypodermis. The skin not only covers the body, but also protects us from bacteria, sun and injuries. Not just safety, the skin also controls body temperature. If the heat occurs, sweat comes out and shrinks the skin in the cold. The skin helps make vitamin D out of sunlight. It is necessary for the strength of bones. Your skin changes itself completely every 28 to 30 days with new cells. Each year, about 4 kg of dead skin falls out of your body. There are millions of nerve ends under the skin that make us touch, make heat, cold and pain. This makes the skin the largest sensory organs. The top layer of the skin is like a waterproof shield. It does not allow external harmful things to enter the body. The skin color is determined by a pigment called melanin.
