Enema
Colon is divided into several distinct regions, ascending colon, right colic flexure, transverse colon, left colic flexure, descending colon, sigmoid colon. The Colon is part of the large intestine.Large intestine is connected to small intestine through ileocecal valve and is about 5 feet long. It ends at the anus, encircles small intestine on 3 sides and has subdivisions called the cecum, vermiform, appendix, colon, rectum, anal canal.There is no difference between the colon and large intestine. Colon is just another word for large intestine.Actually: The colon is the largest part of the large intestine, there is a descending, transverse, and ascending colon, right and left colic flexure, as well as the sigmoid colon, these are all parts of the colon.However the colon is not the only part of the large intestine, there are also the cecum, vermiform appendix, rectum, and anal canal.Therefore the colon carries it towards the rectum, but the rectum is not part of the colon.
Barium enema
The study of the rectum, anus and colon is called proctology.
The large intestine consists of three distinct regions: 1) the cecum, 2) the colon, and 3) the rectum. The cecum is the first section of the large intestine below the ileocecal valve. The appendix is attached to the cecum. Since the colon (ascending, transverse, descending, and sigmoid colon) is the largest region of the large intestine, the term "colon" is often applied to the entire large intestine. The rectum (rectum, anal canal, and anus) is the final region of the large intestine and the end of the digestive tract
