Trying to learn how different blood cells defend against parasites for a story I’m writing and I’m having trouble finding simple explanations for them. I don’t know a lot about terminology used for different types. Particularly I’m looking for stuff based on eosinophils since I’ve heard they have a hand in it. Regardless anything helps thank you. Thank you.

Parasites are too big to be taken up by our cells. So the first thing that need to happen is that the parasite needs to be destoyed. Our immune system does this mostly by poking holes in the cell membrane of the parasite. This is done by the eosinophiles themselves and the complement system. It’s pretty neat, the enzymes from the eosinophiles will disrupt the bounds between lipids within the cell membrane of the parasite, causing it to dissintegrate. The complement system organizes it’s components so that it will make little tunnels in the membrane, water can now flow into the parasite and it will burst like an overly inflated balloon. Poof.
After the parasite is destroyed it will fall apart and the debris is ‘eaten’ up by macrophages (and also the eosinophiles themselves I think).
