The skin is the outer covering of the body. It performs very important function, it is necessary to understand the structure of the skin and how to take care of it. The skin is made up of two main layers, viz:

  1. The Epidermis: this is the outer layer; it has no blood vessel or nerves. It is covered with hair and tiny holes called sweat pores. Sweat passes out through the pores.
  2. The Dermis: this is the inner layer of the skin. It is made up of the following:
  3. Sweat gland which produce sweat
  4. Oil gland which produces oil that keeps the skin and hair soft and fresh.
  • Blood vessels and nerves which keep the skin healthy and help it to perform its functions
  1. Fat deposit which reduce heat loss from the body.
