describe development of pancreas The pancreas develops from two endodermal buds of the foregut: Dorsal pancreatic bud → forms most of the pancreas: body, tail, and part of the head. Ventral pancreatic bud → forms the uncinate process and inferior/posterior part of the head. During development, the ventral bud rotates posteriorly with the bile duct around the duodenum and fuses with the dorsal bud. Duct formation: Main pancreatic duct (duct of Wirsung) = ventral duct + distal part of dorsal duct Accessory pancreatic duct (duct of Santorini) = proximal part of dorsal duct Opening into duodenum: Main duct joins the common bile duct → opens at the major duodenal papilla. Accessory duct may open at the minor duodenal papilla. [image: 1773989803488-d4d51eaf-1914-4bef-b547-4fce2a4566c9-image.jpeg]
