During embryonic development, which structure carries the ventral pancreatic bud and the common bile duct around it?

• A. Stomach
• B. Duodenum
• C. Jejunum
• D. Ileum

Answer: (B)

During foregut development, the ventral pancreatic bud and the common bile duct originate near the hepatic diverticulum and must reach the dorsal pancreatic bud to fuse. The stomach rotates clockwise, and the duodenum forms a C-shaped loop. As this happens, the ventral bud and the bile duct are carried behind the stomach and pass around the duodenum to reach the opposite side, where they fuse with the dorsal bud to form the pancreas. This routing around the duodenum explains why that structure is the one that carries them during development. The bile duct eventually enters the second part of the duodenum, consistent with this arrangement.
