what duct empties into the duodenum
The pancreatic duct empties into the duodenum at the duodenal. papilla, alongside the common bile duct (Figure 4). Figure 4. Normal anatomy. The duct of Wirsung is the main pancreatic duct extending from the tail of the organ to the major duodenal papilla, or ampulla of Vater. The widest part of the duct is in. the head of the pancreas (4 mm), tapering to 2 mm at the tail in adults. The duct of Wirsung is close, and almost parallel, to the distal common bile duct before. combining to form a common duct channel prior to approaching the duodenum.
