Our Immune System
Everyday our body is exposed to millions of germs. Our body protects us in many ways.
- Skin is a protection blanket; it stops germs getting inside you.
- Your nose and mouth have a layer of mucous which traps germs and dust. Saliva and tears have special chemicals which fight off germs.
- White blood cells are the policemen of your blood, always looking for germs and fighting them off.
