What Process Takes Place in the Large Intestine?

The large intestine, located at the end of the digestive tract, absorbs any remaining fluid from undigested material thus converting it to solid waste. This is the final stage of digestion, where remaining nutrients are taken in by the body and undigested matter is prepared for excretion.

The large intestine comprises three main parts: the cecum, a pouch that transition undigested food from the small to the large intestine; the colon, where food goes through the final processes of digestion; and the rectum, where feces are stored until they are passed through the anus. Waste is typically in liquid form when entering the large intestine, but healthy bacteria in the body continue to break down this undigested matter and produce vitamin K. Intestinal mucus absorbs any remaining water from waste, adding bulk to stool before passing it into the rectum.
