The Immune System

Viruses and bacterua are commonly called "Germs". Germs are always trying to enter into our bodies. When they come into your bodies, they start to mutilply, kind of like having babys. Germs make you sick by prouducing toxins which destory cells. Your immune system works to help you from getting sick. Our skin is the largest part of our immune system and is the first line of defense against germs. Our skin produces anti-bacterial sub-stances that keep bacteria from growning in or on you skin.Our skin cannot keep out all the germs thta try to come into our bodies. Germs can enter into our body through every part of our body. Tears and saliva both contain enzymes that help break down bacteria before they have chances to do anything bad to our bodies.
