The pancreatic ducts allow transport of pancreatic fluids from the many |lobules| (small |lobes|) of the |pancreas| to the |duodenum| of the intestine. The principle, or primary, pancreatic duct, also called the canal of Wirsung, is the main duct which accepts contributions of fluid from the many tributary ducts leading from these |lobules|. An |accessory pancreatic duct| is occasionally found to branch off of the primary pancreatic duct in the neck of the |pancreas| and opens into the |duodenum| about an inch above the opening of the primary pancreatic duct.
