Which of the following ducts connects the gallbladder to the common bile duct?

The cystic duct is the structure that connects the gallbladder to the common bile duct, facilitating the flow of bile. This duct allows bile, stored in the gallbladder, to travel to the common bile duct where it can then be released into the duodenum as needed for digestion.

In terms of its anatomy and role in the biliary system, the cystic duct has a crucial function. It is responsible for transporting bile both to and from the gallbladder, depending on whether bile is being released for digestion or being stored for later use.

The left and right hepatic ducts serve a different purpose, as they are responsible for transporting bile from the liver to the common bile duct, rather than connecting the gallbladder. Meanwhile, the common hepatic duct is formed from the merging of the left and right hepatic ducts and plays a role in directing bile from the liver, but does not directly connect to the gallbladder. Thus, the cystic duct is the specific duct that serves the function of connecting the gallbladder to the common bile duct.
