Secretin inhibits production of__________________?
Correct answer: A. Gastric juice
- A. Gastric juice
- B. Pancreatic juice
- C. Bile
- D. All of these
Explanation
Secretin is released by the duodenum when acidic chyme enters it, and it reduces gastric activity while promoting pancreatic bicarbonate secretion. This helps neutralise acid in the small intestine. The likely distractor is pancreatic juice because secretin affects the pancreas, but it stimulates bicarbonate-rich pancreatic secretion rather than inhibiting it.
