biliary tree in dogs

A complex network of conduits that begins with the canals of Hering (intralobar bile duct) and progressively merges into a system of interlobular, septal, and major ducts which then coalesce to form the extrahepatic bile ducts, which finally deliver bile to the intestine, and in some species to the gallbladder. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the biliary tree is

A complex network of conduits that begins with the canals of Hering (intralobar bile duct) and progressively merges into a system of interlobular, septal, and major ducts which then coalesce to form the extrahepatic bile ducts, which finally deliver bile to the intestine, and in some species to the gallbladder. The atlas records it as a organ at the organ scale in the dog.

Where the biliary tree is

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

What the biliary tree connects to

The atlas records 15 typed relationships for it, across 6 kinds of connection. part of biliary system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the biliary tree. 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 biliary tree?

What does the biliary tree connect to?

Part of: biliary system.

Is the biliary tree the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
