A duct joining the pancreas to the common bile duct to supply pancreatic juices which aid in digestion provided by the exocrine pancreas. The pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla.

Upon reaching its final destination, the ventral pancreatic bud fuses with the much larger dorsal pancreatic bud. At this point of fusion, the main ducts of the ventral and dorsal pancreatic buds fuse, forming the duct of Wirsung, the main pancreatic duct.

in EHDAA2 this is an epithelium, in FMA the wall consists of epithelium and connective tissue

These data show that ducts within the zebrafish pancreas originally arise in situ from isolated progenitor cells rather than arising from reiterative branching of the pancreatic epithelium. 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]
