How does your body prevent micro organisms getting into it?
If you damage your skin platelets in your blood form clots which dries as a scab which stops pathogens getting into the your body. When breathing, your breathing organs produce Muscus which traps the microorganisms it is then swallowed and destroyed by your stomach acid.
