The Colon The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the cecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts – ascending, transverse, descending and sigmoid.

Understanding Colorectal Cancer -- The Basics Inside your abdominal cavity is the long, tubular digestive tract. The second part of this tube -- the large intestine -- is composed of the colon, which stretches 4 feet to 6 feet, and the rectum, which is only 4 inches to 6 inches long. The inner lining of this colorectal tube can be a fertile breeding ground for small tumors, called polyps (Figure 1).

Clinical Case ReportsEndoscopic Decompression, Detorsion, and Reduction of Sigmoid Volvulus â Colonic volvulus is a loop of bowel twisted around the site of mesenteric attachment leading to bowel obstruction. The sigmoid colon is involved in a majority of these cases. If untreated, sigmoid volvulus leads to bowel ischemia, perforation, sepsis, and potential death.

Brake Rotors: When To Resurface And When To Replace As inexpensive as many aftermarket rotors are today, it’s quite affordable to simply replace the rotors rather than resurface them. Some auto parts stores offer free resurfacing to customers who purchase pads, while others charge a nominal fee for resurfacing ($10 to $20 per rotor). New rotors should be ready to install right out of the box. There should be no need to “clean them up” with a shallow cut on a lathe.

What is the Ascending Colon? The ascending colon is one part of four sections of the large intestine. This first section of the large intestine is connected to the small intestine by a section of bowel called the cecum. The ascending colon runs through the abdominal cavity, upwards toward the transverse colon for approximately eight inches (20 cm).s the waste material exits the small intestine it will move into the cecum and then the ascending colon where this process of extracting starts. The waste material is moved upwards toward the transverse section of the colon by a process called peristalsis.

S shaped portion of colon? The sigmoid colon (pelvic colon) is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 40 cm in length, and normally lies within the pelvis, but on account of its freedom of movement it is liable to be displaced into the abdominal cavity.

What is the Sigmoid Colon? The sigmoid colon is the end portion of the large intestine, nearest the rectum. This portion of the intestine is in the form of an s-shaped loop, and is usually approximately 16 inches (40.64 cm) in length. It is able to expand and contract dependent upon the amount of fecal material being stored until it is ready to be evacuated from the body.

Large intestine The intestinal glands in the colon are often referred to as colonic crypts. The epithelial inner surface of the colon is punctuated by invaginations, the colonic crypts. The colon crypts are shaped like microscopic thick walled test tubes with a central hole down the length of the tube (the crypt lumen).
