The last section of the large intestine in our body is referred to as the sigmoid colon, the pelvic colon, or the sigmoid flexure. It derives its name due to its S-shaped structure. In Greek, 'S' is usually referred to as 'Sigmoid', hence the name. This S-shaped loop is located near the rectum and is usually around 15 to 16 inches in length. Although it is supposed to lie within the pelvis, due to its freedom of movement, there are chances of it being found in the abdominal cavity. Its main function is to channelize the waste products from the body after digestion, towards the anus. It is also the point or the place where the waste materials collects.

Colon Cancer

Diverticulosis
Diverticulosis occurs when the intestinal wall, mainly in the large intestine, develops several abnormal pouches. This commonly occurs in people above the age of 40. The main cause of this inflammation is unknown. However, doctors believe that factors such as aging, changes in the intestinal pressure, diet that is low in fiber, passing of waste through the colon, and sometimes physical abnormalities may trigger diverticulosis. Some of the symptoms of this problem might be pain, fever, irregular bowel movement, etc.
The terminal section of the large intestine plays a vital role in storage of fecal matter and its expulsion. The medical conditions associated with this part of the large intestine can be prevented to a great extent by following a healthy diet and exercise regimen.
