Which colon segment is located closest to the rectum?

Which colon segment is located closest to the rectum?

• A. Ascending colon
• B. Cecum
• C. Descending colon
• D. Sigmoid

Answer: (D)

The sigmoid colon is the part of the large intestine that sits right next to the rectum. It’s an S-shaped segment that turns into the rectum as it moves into the pelvis, so its location is closest to the rectal area. The other sections—cecum, ascending colon, and descending colon—are positioned higher up in the abdomen (cecum in the lower right, ascending on the right side, descending on the left), so they are farther from the rectum.
