Zoology - Digestion and Absorption Question with Solution | TestHub

The exocrine part of the pancreas consists of rounded lobules (acini) that secrete an alkaline pancreatic juice with $\mathrm{pH}$ 8.4. The pancreatic juice is carried by the main pancreatic duct into the duodenum through the hepatopancreatic ampulla. The accessory pancreatic duct directly pours the pancreatic juice into the duodenum. The pancreatic juice contains sodium bicarbonate, three proenzymes; trypsinogen, chymotrypsinogen and procarboxypeptidase and some enzymes such as elastase, pancreatic $\alpha$-amylase, DNase, RNase and pancreatic lipase. The pancreatic juice helps in the digestion of starch, proteins, fats and nucleic acids.
