Final answer:
Cholecystokinin (CCK) inhibits gastric emptying and gastric acid secretion while stimulating the release of bile and pancreatic enzymes. Secretin inhibits gastric acid secretion and stimulates bicarbonate release from the pancreas to neutralize chyme in the duodenum.
Step-by-step explanation:
Cholecystokinin (CCK) and secretin are two hormones involved in the digestive process. CCK primarily inhibits gastric emptying and gastric acid secretion as it stimulates the gallbladder to release bile and the pancreas to release its digestive enzymes. On the other hand, secretin inhibits the secretion of gastric acid from the stomach as it promotes the secretion of bicarbonate from the pancreas, which neutralizes the acidic chyme in the duodenum. These hormones work in tandem not just for digestion but also for regulating the pace at which food moves through the digestive system.
