Answer :
Final answer:
Pancreatic acini are the structures in the pancreas which secrete large quantities of an alkaline, enzyme-rich fluid for digestion in the duodenum.
Explanation:
The pancreatic structure which secretes large quantities of an alkaline, enzyme-rich fluid used in digestion in the duodenum is the pancreatic acini. The pancreas, an essential organ in the digestive system, is composed of different types of cells each with their specific functions. Alpha cells produce glucagon - a hormone shaping glucose metabolism, and delta cells are responsible for the production of somatostatin, a hormone that inhibits insulin and glucagon secretion. Pancreatic islets include both these types of cells along with few others, but none secrete digestion aiding fluids. On the other hand, pancreatic acini are clusters of exocrine cells that secrete a variety of enzymes, including lipase, protease, and amylase, into the small intestine or duodenum to aid the process of digestion.
