What is the correct order of sections of the large intestine from beginning to end?

• A. Cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum
• B. Rectum, sigmoid, transverse, ascending, descending, cecum
• C. Cecum, descending, rectum, ascending, transverse, sigmoid
• D. Sigmoid, cecum, ascending, transverse, descending, rectum

Answer: (A)

From the ileocecal junction to the anal canal, the large intestine follows a defined path: cecum, ascending colon, transverse colon, descending colon, sigmoid colon, then rectum. The cecum marks where contents from the ileum enter the large intestine, with the ascending colon continuing upward on the right side, then the transverse colon crossing the abdomen at the hepatic flexure, followed by the descending colon on the left, the S-shaped sigmoid colon, and finally the rectum leading to the anal canal. This order reflects how material moves through the colon for water absorption and feces formation, ending with storage in the rectum before defecation. The other sequences place segments out of this progression (for example starting at the end or jumbling the flexures), so they don’t match the actual anatomical flow.
