The biliary tract (biliary tree or biliary system) functions to make, store, and secrete bile. First the liver makes bile, which travels through the right and left hepatic ducts into the common hepatic duct. Where will it go next? The common bile duct or the cystic duct that can be stored in the gallbladder. Then the bile from the gallbladder will get squeezed out by cholecystokinin. That bile then goes into the common bile duct. The bile from the common bile duct will go into the duodenum. The other bile that went into the common bile duct will go into the duodenum too.
