Which hormone stimulates the release of bicarbonate and pancreatic enzymes?

The hormone that stimulates the release of bicarbonate and pancreatic enzymes is secretin. This hormone is produced by the S cells of the duodenum in response to acidic chyme entering from the stomach. When secretin is released into the bloodstream, it prompts the pancreas to secrete a bicarbonate-rich fluid, which helps to neutralize stomach acid in the small intestine. Additionally, secretin works synergistically with cholecystokinin (CCK) to enhance the secretion of digestive enzymes from the pancreas, making it vital for proper digestion.

Understanding the role of secretin in this process highlights its importance in maintaining the pH balance in the small intestine and facilitating effective digestion, showing why it is the correct answer to the question regarding stimulation of bicarbonate and pancreatic enzyme release.
