All passageways inside and outside the liver that carry bile to the intestines.

The biliary tree is the common anatomic term for the path by which bile is secreted by the liver on its way to the duodenum, or small intestine, of most members of the mammal family. It is referred to as a tree because it begins with many small branches which end in the common bile duct, sometimes referred to as the trunk of the biliary tree.
