Structures opening in the 2nd part of the duodenum

The bile duct unites with the pancreatic duct forming a dilatation called the hepatopancreatic ampulla (ampulla of Vater).

The ampulla opens on an elevation called the major duodenal papilla.

The accessory pancreatic duct opens one-inch above the major duodenal papilla, forming a smaller elevation called the minor duodenal papilla.
