colon
Description
The longest part of the large intestine that receives almost completely digested food from the cecum (the first part of the large intestine), absorbs water and nutrients and passes waste (stool or feces) to the rectum.
The colon is made up of 4 parts. The ascending colon starts at the cecum and goes up the right side of the abdomen. The transverse colon goes across the upper abdomen. The descending colon goes down the left side of the abdomen. The sigmoid colon is the last part of the colon that connects the descending colon to the rectum.
Sometimes called the lower intestine or large bowel.
