Which duodenal hormone stimulates the secretion of pancreatic enzymes and bile release from the liver and gallbladder?

1. Several hormones produced by the duodenum help regulate digestion once chyme arrives from the stomach. 2. Secretin stimulates a watery, bicarbonate-rich secretion from the pancreas. 3. Cholecystokinin (CCK) is the hormone that stimulates secretion of pancreatic enzymes and release of bile from the liver and gallbladder. 4. Gastrin instead mainly stimulates gastric acid secretion in the stomach, and gastric inhibitory peptide inhibits gastric secretion and motility so neither matches the enzyme- and bile-stimulating role described here. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.2, p. 1097_
