bile duct

tube that carries bile from the liver or gallbladder to the small intestines (Anatomy)

A bile duct is any of a number of long tube-like structures that carry bile.Bile, required for the digestion of food, is excreted by the liver into passages that carry bile toward the hepatic duct, which joins with the cystic duct (carrying bile to and from the gallbladder) to form the common bile duct, which opens into the intestine. The biliary tree (see below) is the whole network of various sized ducts branching through the liver.
