The colon, also referred to asÂ the large intestine, is the last section of the digestive tract. The colon consists of the cecum,Â the ascending colon, transverse colon, descending colon, sigmoid colon and rectum. Â While the cecum is the first section of colon that is found in the lower right abdominal region, the rectum is the last region where stool is stored.
The colon is about 5 feet in length and 3 inches in diameter. The colon's function is to absorb salts, water and other nutrients from waste products to form stool.
The process of digestion involves food traveling from the mouth to the different parts of the digestive tract, which include the esophagus, stomach, small intestine and large intestine.
