The sigmoid colon is the part of the large intestine after the descending colon and before the rectum. The name sigmoid means S-shaped (see sigmoid; cf. sigmoid sinus). The walls of the sigmoid colon are muscular, and contract to increase the pressure inside the colon, causing the stool to move into the rectum.

Mapping the body: the sigmoid colon. The sigmoid colon is towards the bottom right of the large intestine. It is usually patients not doctors who balk at the sight of a medical instrument being unwrapped. But the flatus tube, used to treat a condition of the sigmoid colon, is one no surgeon relishes. The sigmoid is an S-shaped stretch of large bowel, about 40cm long, which leads up to the rectum.

The transverse colon is the part of the colon from the hepatic flexure to the splenic flexure (the turn of the colon by the spleen). The transverse colon hangs off the stomach, attached to it by a large fold of peritoneum called the greater omentum.

Inflammatory bowel disease such as ulcerative colitis and Crohn's disease may occur here. Diverticulitis, in which little outpouchings of bowel form and become inflamed, is more common in the sigmoid than any other part of the bowel. Small growths called polyps, as well as cancers, also favour this site. The good thing about investigating sigmoid disease is that this part of the colon isn't far from the outside world. It is easy to pass a rigid sigmoidoscope into the anus and get a decent view.

The large intestine, or the large bowel, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation.

Resection is another name for any operation that removes tissue or part of an organ. Bowel resection , also called partial colectomy, removes a diseased or damaged part of the colon or rectum. Bowel resection can be done for many diseases that affect the colon, such as colorectal cancer, diverticulitis, or Crohn's disease. The goal of bowel resection is to take out the part of the colon or rectum where the problem is. If the doctor is removing cancer from the colon, nearby lymph nodes are taken out and tested for cancer. Then healthy parts of the colon or rectum are sewn back together.

The colon is the last part of the digestive system. It extracts water and salt from solid wastes before they are eliminated from the body and is the site in which flora-aided (largely bacterial) fermentation of unabsorbed material occurs.

The descending colon is the part of the colon from the splenic flexure to the beginning of the sigmoid colon. One function of the descending colon in the digestive system is to store feces that will be emptied into the rectum. It is retroperitoneal in two-thirds of humans.
