Verified step by step guidance

1. Understand the anatomy of the colon: The colon is divided into several sections, including the ascending colon, transverse colon, descending colon, and sigmoid colon. Each section has a specific location and function in the digestive system.
2. Define the term 'proximal': In anatomy, 'proximal' refers to a structure that is closer to the point of origin or attachment. For the colon, the point of origin is the cecum, where the large intestine begins.
3. Identify the section of the colon closest to the cecum: The ascending colon is the first section of the colon and is located immediately after the cecum. It travels upward on the right side of the abdomen.
4. Compare the other options: The transverse colon is located horizontally across the abdomen, the descending colon travels downward on the left side, and the sigmoid colon is the S-shaped section near the rectum. These sections are farther from the cecum and are not considered proximal.
5. Conclude that the ascending colon is another term for the proximal colon, as it is the section closest to the cecum and the beginning of the large intestine.
