Wow, talk about a detailed overview. I have to do a paper on white blood cells for my bio class next week, and I was kind of bored with it, but after reading how the three kinds of cells interact, I'm actually kind of interested.
Cool how everything in the body can work together, right?
I do have one question though -- what happens if one of the types of white blood cells don't work properly, for instance, if the granulocytes just didn't respond to the chemical signals? Is there some sort of backup system in place, or would a person be pretty much doomed?
