Which structure is part of the large intestine?

• A. Duodenum, ileum
• B. Cecum, colon, rectum, anal canal, anus
• C. Esophagus
• D. Pancreas

Answer: (B)

The large intestine is composed of the cecum, colon, rectum, anal canal, and anus. The cecum connects to the ileum of the small intestine, and the colon is where water absorption and stool formation occur, while the rectum and anal canal handle storage and passage of feces. The other options belong to different parts of the digestive system: the duodenum and ileum are sections of the small intestine, the esophagus is the tube from the mouth to the stomach, and the pancreas is an accessory digestive organ. So, the listed structures are the components of the large intestine.
