Module 1. Understanding and Preparing for Colonoscopy

What does the colon do?

The colon plays an important role in the digestive system. In this video, gastroenterologists Drs. Echavarria and Gelrud explain some of the colon’s important functions - such as the absorption of water from undigested food to produce stool (feces), the accumulation and delivery of stool to the rectum prior to a bowel movement, and the absorption of certain nutrients that are important for the maintenance of good health. Additionally, the experts discuss how a colonoscopy procedure is helpful in cases where the colon is diseased, inflamed, or infected, and to screen for colon cancer.
