HUMAN NUTRITION

Detailed explanation-1: -A large main duct, the duct of Wirsung, collects pancreatic juice and empties into the duodenum. In many individuals a smaller duct (the duct of Santorini) also empties into the duodenum. Enzymes active in the digestion of carbohydrates, fat, and protein continuously flow from the pancreas through these ducts.

Detailed explanation-2: -The pancreatic duct delivers exocrine secretions into the duodenum. The ductal cells secrete fluid and bicarbonate ions, which neutralize acinar cell secretions, as well as the acidic gastric contents entering the duodenum (110).

Detailed explanation-3: -The pancreas produces an exocrine secretion (pancreatic juice from the acinar cells) which then enters the duodenum through the main and accessory pancreatic ducts and endocrine secretions (glucagon and insulin from the pancreatic islets of Langerhans) that enter the blood.

Detailed explanation-4: -The common bile duct and one pancreatic duct enter the duodenum via the major papilla.
