TOPIC: The Human Body (III)
The skin is the outer covering of the body.
Structure of the Skin
The skin is made up of two main layers – the epidermis and the dermis or “true skin.”
The Epidermis – This is the outer layer. It has no blood vessels or nerves. It is covered with hairs and tiny holes called sweat pores. Sweat or perspiration passes out through the pores.
The Dermis – This is the inner layer of the skin. It is made up of the following:
(i) Sweat glands which produce sweat.
(ii) Oil glands which produce oil that keeps the skin and hair fresh and soft.
(iii) Blood vessels and nerves which keep the skin healthy and help it to perform its functions.
(iv) Fat deposits which reduce heat loss from the body.
