Final answer:
The large intestine is composed of the cecum, colon, and rectum. In terms of relative lengths, the largest is the colon, followed by the cecum, and finally the rectum.
Step-by-step explanation:
Anatomy of the Large Intestine
The anatomy of the large intestine includes several regions: the cecum, the colon, and the rectum. The cecum is the initial section where chyme from the small intestine enters. Attached to it is the appendix, a vestigial organ. The colon can be further divided into four parts: the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which eventually leads to the rectum. The rectum serves as storage for feces before they are excreted through the anus.
The correct order in relative lengths of each section from longest to shortest would be: Colon, Cecum, Rectum (Option d).
To quantify, the colon is the longest section, divided into several parts to facilitate the absorption of water and mineral salts. The cecum acts as a receiving pouch and includes the appendix. The rectum is the final stage of the large intestine leading to the anus, responsible for storing feces before defecation.
