Large Intestine Quiz – How Your Colon Absorbs Water

The large intestine is about 1.5 meters long and wider than the small intestine, which is why it is called large. It begins at the cecum, where the appendix hangs, and continues through the ascending, transverse, descending and sigmoid colon.

Its main job is absorbing water and salts, turning liquid leftovers into solid waste. Pouches called haustra and slow waves of muscle move the contents along.

Trillions of bacteria live here, fermenting fiber into useful fatty acids and helping produce vitamin K. Waste is stored in the rectum until it leaves the body.
