Most digestive enzymes in the small intestine are located in:
  1. The ileocecal valve
  2. The brush border
  3. The duodenojejunal flexure
  4. The pyloric sphincter
Explanation
Answer: B - Most digestive enzymes in the small intestine are located in the brush border, which is a level of microvilli lining the surface of the intestinal wall. The ileocecal valves allows food to pass from the jejunum to the ileum. The duodenojejunal flexure is the junction between the duodenum and the jejunum, and the pyloric sphincter is the passage between the stomach and the duodenum
