The white cells are your body’s House Detectives. Most of the time they lounge around the bloodstream, telling jokes and forming the occasional cyst. But they swing into action the instant your body is invaded by one of the many enemy organisms that can get into your bloodstream, these being bacteria, viruses, rotifers, conifers, parameciums, cholesterol, tiny little lockjaw germs that dwell on the ends of all sharp objects, antacids, riboflavin, and the plague. As soon as the white cells spot one of these, they drop whatever they’re doing and pursue it on a wild and often hilarious chase through your various organs, which sometimes results in damage to innocent tissue. Eventually they catch the invader and tie its tentacles behind its back with antibodies, which are the body’s Handcuffs, and deport it via the bowel.

Of course this is just a brief rundown on your various organs and systems; in the short space I have here, it’s very difficult for me to explain all of your body’s complexities and subtleties in any detail, or even get any facts right. For more information, I suggest you attend Harvard Medical School, which I believe is in Wisconsin.
