Which of the following is NOT one of the three major regions of the large intestine?

Explanation:
The large intestine is organized into three main regions: the cecum, the colon, and the rectum. The sigmoid colon is not considered a separate major region; it is part of the colon, forming the S-shaped segment that lies in the pelvis and connects the colon to the rectum. So, describing the sigmoid colon as a distinct major region would be incorrect, since it falls under the colon. The cecum with its appendix and the rectum are the other two major regions, matching the standard anatomical divisions.
