However, some have an additional accessory pancreatic duct also called the Duct of Santorini, which connects straight to the duodenum at the minor duodenal papilla. Both these ducts connect to the second part (the vertical one) of the duodenum. However, the Duct of Santorini, which bypasses the Ampulla of Vater, is non-functional whereas the Duct of Wirsung is functional and carries the digestive enzymes released by the pancreas. It is named for Giovanni Domenico Santorini accessory pancreatic duct of santorini A pancreatic duct that develops from the dorsal pancreatic bud.

This process of pancreatic duct formation in zebrafish may be analogous to the mechanism of duct formation in the mammalian mammary and salivary glands. (...) A related mechanism of duct formation has also been proposed to occur within the mammalian pancreatic epithelium.[uncertain][VHOG] MA:0000125 pancreatic duct of santorini FMA:14534 ductus pancreaticus accessorius accessory pancreatic duct EMAPA:32953 EHDAA:9188 pancreatic duct
