Skin is important organ of the human body. It covers all of the body and performs many special functions.

Skin is the largest organ in the human body. It weights between two and three kilograms and is either glabrous or hairy. Glabrous skin is that found on the palms of the hands and the souls of the feet. It is smooth and hairless. Hairy skin covers the rest of the body and this varies in texture, thickness and amount of hair.

Skin is made up of two layers. The outer layer is the epidermis. This is mainly dead or dying skin cells. Beneath the epidermis is the dermis. The dermis is made from tougher fibres and is thicker than the epidermis. Within the dermis are nerves, blood vessels and glands.

Skin does a number of important things for the body. It provides a protective covering for the body from drying out, hols the body organs in place and regulates the body's temperature.

The skin, therefore, is a complex part of the human body.
