Describe how the human body prevents pathogens from entering and defends itself against pathogens inside the body
-skin acts as a barrier ,oil on the surface that repels pathogens
-Eyes produce tears which are antiseptic-contains enzymes that could kill bacteria
-Trachea,bronchi and the nose-contains mucus-sticky,traps bacteria-carried away by the cilia
-White blood cells-immune system-memory cells-which triggers a rapid response is pathogen reenters
Antitoxins-neutralises Antibodies-produced and helps destroy them
