Role in digestion

The large intestine comes after the small intestine in the digestive tract and measures approximately 1.5m in length.

By the time the chyme has reached this tube, almost all nutrients have been absorbed by the body and only water and some electrolytes like sodium and chloride are left. As the chyme moves through the large intestine, water is removed, while the chyme is mixed with mucus and bacteria, and becomes feces. The large intestine produces no digestive enzymes — chemical digestion is completed in the small intestine before the chyme reaches the large intestine. The pH in the colon varies between 5.5 and 7 (neutral or slightly acidic). Chyme is the liquid substance found in the stomach before passing the pyloric valve and entering the duodenum. ...
