What do the white blood cells do to the microbes?

Answer 1

They can engulf them just by chasing them and eating them or if there's a lot of them they can make them all stick together and engulf them all at once. They can also make them burst. If they are toxins, the white blood cell can produce antitoxins to kill them. You can think of this like a recipe. The white blood cell needs to find a recipe to kill the foreign microbe and that is why you can be ill for a long time. This is also why you can become immune to something. You can get a virus and the white blood cells take 2 days to find the correct antitoxin to kill it, and if the virus comes back then your white blood cells already have the correct recipe to kill it.

Hope this helps. :)
