CHILD’S HEALTH/SKIN DISORDERS: WHAT DOES THE SKIN DO?
The skin is more than just a wrapping for the rest of the body. It is, in fact, the body’s largest organ and performs many complex roles. It serves as a protective barrier against physical and chemical insults from the outside world. It also helps to keep vital fluids and body chemicals from escaping from the body. Other functions of the skin include control of body temperature, the secretion of substances, sensation (e.g. pain, touch), and the formation of pigment (skin colour).
The skin has several layers, each of which has a different function. The outer layer, or epidermis, provides a protective barrier. It renews itself approximately every 28 days. The next layer, the dermis, acts as a support structure for blood vessels and sweat glands, which play a vital role in the body’s temperature control system. The nerves, hair follicles and lymphatics (which act as a kind of filter and thus play an important role in the immune system) are also found in this layer.
