Before that the pathogens have to get through: Once they get into your body these things to stop it: The white-ish ones are the white blood cells floating in the plasma of a blood vessel. Antibodies are little cells that grip onto a pathogen to feel it's texture (kinds of pathogens all have different textures) so your body can build a defence against it.
