What part of the digestive system connects the stomach and the large intestine?

• A. Duodenum
• B. Small intestine
• C. Esophagus
• D. Rectum

Answer: (B)

The small intestine is the correct answer because it serves as the segment of the digestive system that connects the stomach to the large intestine. The small intestine is comprised of three parts: the duodenum, jejunum, and ileum. After food exits the stomach, it enters the duodenum, where it mixes with digestive juices from the pancreas and liver. From the duodenum, the partially digested food continues through the jejunum and ileum before reaching the large intestine. The other options do not fulfill this role in the digestive system. The duodenum is specifically the first section of the small intestine rather than a standalone entity connecting directly to the large intestine. The esophagus, on the other hand, connects the throat to the stomach, playing no part in the transition between the stomach and the large intestine. Lastly, the rectum is the final section of the large intestine and serves as a storage site for feces before they are excreted, further removed from the connection between the stomach and the large intestine.
