  • Foreign substances may enter through skin, mucous membranes, food or water, and air.
  • The body defence system has local defence and immune defence.
  • Skin, hair, mucus, and cilia help stop germs.
  • Coughing, sneezing, vomiting, and diarrhoea help throw out germs.
  • Saliva, sweat, tears, nasal secretions, and stomach acid help kill germs.

Common Mistakes to Avoid
