Question: 1 / 400

What is the part of the large intestine between the descending colon and the rectum called?

Sigmoid colon

The part of the large intestine located between the descending colon and the rectum is known as the sigmoid colon. The sigmoid colon is shaped like an "S" and serves as a connector between the descending colon and the rectum, playing a crucial role in storing fecal material prior to elimination. Its structure allows it to facilitate the final stages of digestion and assists in moving the waste toward the rectum.

The other options describe different sections of the large intestine. For instance, the transverse colon runs horizontally across the abdomen, while the cecum is the initial segment of the large intestine that connects to the ileum of the small intestine. The ascending colon ascends vertically from the cecum to the transverse colon. Understanding the anatomical placement and function of the sigmoid colon within the digestive system is essential for comprehending how waste is processed and expelled from the body.
