Rectum - Bringing up the Rear

Rectum - Bringing up the Rear
The rectum is the last stop for poop! The butt of many jokes, the rectum plays a serious role when it comes to pooping. This fecal loading dock is lined with nerve endings that, when filled with poop, tell the brain to find a bathroom pronto. Strong muscles push the poop out of the rectum and through the anus and, if you’re lucky, into the toilet! Vertical folds in rectum, called the Columns of Morgagni, are named after the lucky Giovanni Battista Morgagni, probably by one of his disgruntled former interns. Butts up! SHOP THIS ORGAN »
