Skin, like the heart and the brain, is actually an organ.
--It is the LARGEST organ in the human body--

IMPORTANCE OF THE SKIN

  1. It forms a shield against water.
    Without skin, water and other liquids could get into your body.
  2. Skin forms protection against disease.
    If someone you knew ever had a cold, your skin helped to protect you from catching the cold. Otherwise, the germs could get through your skin into your body.
  3. It maintains your body temperature.
    Your normal body temperature is 98.6° F. Your skin makes sure that your body temperature stays near there. When your body temperature goes up or down too much, you may be sick.
  4. Your skin is also a sense organ.
    That means that when something touches your skin, you can sense it there without knowing it. When you touch something that is hot, you can feel the heat on your skin. If your skin didn't tell you that, then you might be burned without even knowing.


As you can see, skin is vital to life. Next we will learn about the parts of skin.
