Which set comprises the duodenum, jejunum, and ileum?

• A. Large intestine
• B. Pancreas
• C. Stomach
• D. Small intestine

Answer: (D)

These three sections are all part of the small intestine, the long, highly folded tube where most digestion and nutrient absorption take place. The duodenum is the first segment where chyme mixes with bile and pancreatic juice, the jejunum handles the majority of nutrient absorption, and the ileum finishes absorption and takes up bile acids and vitamin B12. The stomach is the preceding organ that begins digestion, the pancreas is a nearby gland that provides digestive enzymes but isn’t a segment of the intestine, and the large intestine comes after the small intestine and mainly absorbs water. So, the set comprising the duodenum, jejunum, and ileum is the small intestine.
