View of the Liver and Gallbladder. Bile empties from the gallbladder into the common bile duct. The common bile duct joins with the pancreatic duct to form the ampulla of Vater, which empties into the duodenum. Before joining the pancreatic duct, the common bile duct tapers to a diameter of â¤ 0.6 cm. The sphincter of Oddi, which surrounds both the pancreatic duct and the common bile duct, includes a sphincter for each duct. Bile does not normally flow retrograde into the pancreatic duct.
Report Abuse. 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.eport Abuse. The hepatic ducts drain the bile from the liver to the gallbladder. The cystic duct drains bile from the gallbladder to the common duct. the common duct empties into the small intestine, specificall the duodenum at the ampula of Vater (2nd part, I believe...might be the third).
