Which two ducts come together to form the common bile duct?

• A. Cystic duct and common hepatic duct
• B. Ileal duct and jejunal duct
• C. Pancreatic duct and hepatic duct
• D. Mesenteric duct and colonic duct

Answer: (A)

The common bile duct is formed by the conjunction of the cystic duct and the common hepatic duct. The cystic duct transports bile from the gallbladder, where it is stored and concentrated, while the common hepatic duct carries bile from the liver. When these two ducts merge, they create the common bile duct, which plays a critical role in transporting bile to the duodenum for digestion.

Understanding the anatomy and function of the biliary system is essential for radiographic evaluation and procedures involving the liver and gallbladder. The relationship between these ducts is vital, especially in the context of diagnosing and treating conditions like gallstones or cholangitis, where the flow of bile may be obstructed or altered.
