Which one causes the release of pancreatic exocrine secretion?
Correct answer: B. Secretin
- A. Glucose
- B. Secretin
- C. Gastrin
- D. Bile
Explanation
Secretin is a hormone that is released from the small intestine in response to the presence of acidic chyme (partially digested food) coming from the stomach. It stimulates the release of pancreatic exocrine secretion, mainly bicarbonate-rich fluid, which helps in neutralizing the acidic chyme in the small intestine.
