常见问题

What does the exocrine pancreas produce?
The exocrine pancreas produces digestive enzymes in inactive precursor forms called zymogens, including trypsinogen, chymotrypsinogen, proelastase, and prolipase, along with amylase and DNase. These are secreted into the duodenum via the pancreatic duct and activated by intestinal enzymes.
What are acinar cells and what is their role?
Acinar cells are the secretory units of the exocrine pancreas, arranged in grape-like clusters (acini). They synthesize and store zymogen granules containing digestive enzyme precursors and release them in response to hormonal signals (cholecystokinin) and vagal stimulation after a meal.
How is the exocrine pancreatic secretion delivered to the intestine?
Acinar cells secrete enzymes into small intercalated ducts that merge progressively into larger interlobular ducts and ultimately the main pancreatic duct (of Wirsung), which joins the bile duct at the hepatopancreatic ampulla (of Vater) before emptying into the duodenum.
