Which immune system part are you?
We’ve got a thymus plush now! This incredible gland is an important part of the immune system, it works hardest in young bodies and declines after puberty. The thymus, located inside your chest, nestled between your lungs, provides a place for T-cells to mature before they go out and kick some virus, bacteria or parasite booty. Thanks, Thymus! Also, if you’ve ever eaten sweetbreads, that’s the (not human) thymus you’re munching on.
Many of you have written in to suggest making some sort of graphic showing where all the guts and glands live in the body, and I've finally gotten around to creating one. It's even got rollovers so you can learn more about, say, your pineal gland, should you have time to squander. For the purposes of simplicity, we've made the body a hermaphrodite -- she's got a uterus to go with her prostate and testes! We'll call her/him Hermie.
