MICROANATOMY

Detailed explanation-1: -Pancreas secretes fluid rich in digestive enzymes and bicarbonate. The alkaline secretion is important in buffering of acid chyme entering duodenum and for activation of enzymes.

Detailed explanation-2: -The tissues of the pancreas (acinar cells) produce a clear digestive fluid made up of bicarbonate, and enzymes. Bicarbonate is alkaline, and helps digestion by neutralizing the stomach acid containing the food as it passes into the duodenum. The enzymes are more important.

Detailed explanation-3: -The pancreas secretes digestive enzymes into the duodenum and hormones into the bloodstream. The digestive enzymes (such as amylase, lipase, and trypsin) are released from the cells of the acini and flow into the pancreatic duct.

Detailed explanation-4: -The exocrine part of the pancreas arises as little grape-like cell clusters, each called an acinus (plural = acini), located at the terminal ends of pancreatic ducts. These acinar cells secrete enzyme-rich pancreatic juice into tiny merging ducts that form two dominant ducts.
