szigmabél

szigmabél is a term that refers to the sigmoid colon, the final section of the large intestine in the human digestive system. It is located between the descending colon and the rectum. The sigmoid colon is characterized by its S-shape, which gives it its name, derived from the Greek letter sigma. Its primary function is to store fecal matter before it is eliminated from the body. The sigmoid colon also plays a role in regulating the passage of waste through peristalsis, the muscular contractions that move food and waste through the digestive tract.

The structure of the sigmoid colon consists of a muscular wall lined with mucosa, which secretes mucus to lubricate the passage of stool. The length of the sigmoid colon can vary among individuals, and its position can also differ, sometimes extending into the pelvic cavity. Conditions affecting the sigmoid colon can include diverticulitis, a common disorder characterized by inflammation or infection of small pouches that can form in the lining of the digestive system, most often in the sigmoid colon. Other issues include colitis, which is inflammation of the colon, and various forms of polyps or tumors that can develop in this segment of the intestine. Medical examination of the sigmoid colon is often performed using colonoscopy, a procedure that allows visualization of the colon's interior.
