And what does it protect against? a bad case of diarrhea.

An intussusception is a medical condition in which a part of the intestine invaginates (folds into) into another section of intestine, similar to the way the parts of a collapsible telescope slide into one another.[1] This can often result in an obstruction. The part that prolapses into the other is called the intussusceptum, and the part that receives it is called the intussuscipiens. Intussusception is a medical emergency and a patient should be seen immediately to reduce risk.
