Where does the fusion of the common bile duct and the pancreatic duct most commonly occur?
Understand the Problem
The question is asking about the most common location where the common bile duct and the pancreatic duct merge. This requires knowledge of human anatomy, specifically the biliary and pancreatic systems and their relationship to the duodenum.
Answer
The fusion most commonly occurs at the main papilla (of Vater) / hepatopancreatic ampulla before draining into the duodenum.
The fusion of the common bile duct and the pancreatic duct most commonly occurs at the main papilla (of Vater), also known as the hepatopancreatic ampulla, before draining into the second part of the duodenum.
Answer for screen readers
The fusion of the common bile duct and the pancreatic duct most commonly occurs at the main papilla (of Vater), also known as the hepatopancreatic ampulla, before draining into the second part of the duodenum.
More Information
The hepatopancreatic ampulla is also known as the ampulla of Vater. Approximately 70% of the time, the common bile duct and main pancreatic duct join to form a true ampulla while traveling through the duodenal wall.
