The root sigmoid/o is used to refer to which part?

Explanation:
Sigmoid/o names the sigmoid portion of the large intestine—the S-shaped section that curves between the descending colon and the rectum. The root comes from the Greek word meaning “shaped like an S,” describing its distinctive curve. Because of that shape, this root is used specifically for the sigmoid colon in medical terms, not for the ascending colon or the small intestine, which have their own roots, and not for the rectum, which is referred to with rect/o or proct/o. You’ll see terms like sigmoidoscopy referencing this part of the colon.
