common bile duct

The part of the biliary tree formed by the union of the cystic duct and the common hepatic duct. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the common bile duct is

The part of the biliary tree formed by the union of the cystic duct and the common hepatic duct. The atlas records it as a organ at the organ scale in the human body.

Where the common bile duct is

It sits within the digestive system. Only the system is known. The position shown carries almost no spatial information.

What the common bile duct connects to

The atlas records 9 typed relationships for it, across 5 kinds of connection. part of biliary tree.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the common bile duct. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the common bile duct?

What does the common bile duct connect to?

Is the common bile duct the same in other species?
