Abstract
A study of colorectal carcinoma along with different histopathological variants. To study the staging of colorectal carcinoma and the significance of histopathological variants of colorectal carcinoma. The large bowel comprises the terminal 1 to 1.5m of the gastrointestinal tract and is divided into caecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. The hepatic flexure is at the junction of the ascending and transverse colon, and the splenic flexure is at the junction of the transverse and descending colon. The rectum forms the distal 8 to 15cm of extra peritoneal large bowel wall. There are two major functions of the colon and rectum. The colon absorbs water and minerals from blood and transports them into the bloodstream. The rectum stores faecal matter until it is eliminated from the body through the anus. Both organs are essential to the digestive process Caecum, ascending colon and right two thirds of transverse colon are derived from midgut and left one third of transverse colon, descending colon, pelvic colon and rectum are derived from hind gut.
