The portion of the small intestine that comes after the duodenum.

The portion of the small intestine that comes after the duodenum.

• A. Raynaud's disease
• B. Pericardium
• C. Ileum
• D. Duodenum

Answer: (C)

The main idea is knowing how the small intestine is arranged. After the stomach, the first part is the duodenum, then comes the jejunum, and finally the ileum. The jejunum is the section that follows the duodenum, and it’s where most nutrient absorption occurs. The ileum comes after the jejunum, handling absorption processes like bile acids and vitamin B12. In other words, the segment that directly comes after the duodenum is the jejunum; the listed options don’t include that correct term.
