Skin is an important organ of the human body. It covers 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. Hair skin covers the rest of the body and this varies in texture, thickness, and amount of hair.
Skin is made up two layers. The outer layer is 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, helps to prevent the body from drying out, holds the body organs in place, and regulates the body temperature.
The skin, therefore, is a complex part of the human body.
