is gallbladder a bile duct
Overview. A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the pancreas to the small intestine (the duodenum). Bile is a dark-green or yellowish-brown fluid secreted by the liver to digest fats.Much of the bile is released directly into the small intestine, but what remains is stored in the gallbladder.he biliary duct (the duct from the gallbladder) also opens into the common hepatic duct. The bile duct from this point onward is known as the common bile duct or choledochus. Before emptying into the small intestine the common bile duct passes through the pancreas.
