1. 9 Secretin was without effect on gastric smooth muscle activity.

2. Adrenocorticotrophic hormone, secretin, and pancreozymin (cholecystokinin) also depolarized dorsal root terminals and motoneurons.

3. Experience with the secretin-pancreozymin test in 53 children aged 3 months to 16 years is reported.

4. Medium- and long-chain fatty acids were found to be an adequate stimulus for secretion of the gastrointestinal hormones cholecystokinin (CCK) and secretin.

5. The duodenum also produces the hormone secretin to stimulate the pancreatic secretion of large amounts of sodium bicarbonate, which then raises pH of the chyme to 7.

6. Six females had abnormal secretin stimulation of gastrin release but had achlorhydria or hypochlorhydria with other features suggestive of type A atrophic gastritis.

7. Cholecystokinin (CCK), formerly called pancreozymin, a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine (duodenum).

8. Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver.

9. ‘Fiber contributes to the release of Cholecystokinin, a hormone produced in the small intestine that triggers a sensation of satiety in the brain.’ ‘Another hormone from the small intestine, Cholecystokinin, works similarly to secretin.’

10. Secretin helps regulate the pH of the duodenum by (1) inhibiting the secretion of gastric acid from the parietal cells of the stomach and (2) stimulating the production of bicarbonate from the ductal cells of the pancreas.
