Answer :
Final answer:
The statement that secretin and cholecystokinin influence the release of both pancreatic juice and bile is true. Secretin helps release sodium bicarbonate to neutralize acidic chyme, while cholecystokinin stimulates the release of digestive enzymes and bile, essential for fat digestion.
Explanation:
The question "Secretin and cholecystokinin influence the release of both pancreatic juice and bile. The statement is true. Secretin primarily affects the release of sodium bicarbonate from the pancreas, which helps neutralize the acidic chyme in the duodenum. This process is critical for protecting the intestine and ensuring optimal conditions for enzyme activity. On the other hand, cholecystokinin (CCK) stimulates the pancreas to release digestive enzymes and the gallbladder to release bile. Bile plays an essential role in the digestion and absorption of fats. Both hormones work in tandem to coordinate the digestion of food, ensuring that the digestive secretions from the pancreas and gallbladder are released when needed.
