1. Synonym(s): common bile duct
Any of the excretory passages in the liver that carry bile to the hepatic duct, which joins with the cystic duct to form the common bile duct opening into the duodenum. Also called biliary duct.
See biliary duct.
bile ductA generic term for any of the ducts which begin with the bile canaliculi in the liver, converging in turn with the canals of Hering, the interlobular bile ducts, intrahepatic bile ducts, and the left and right hepatic ducts to become the common hepatic duct, which exits the liver and joins the cystic duct forming the common bile duct. The common hepatic duct and the cystic duct are regarded as the “bile ducts”, which then enter the pancreas, merge with pancreatic duct, dilate to form the ampulla of Vater, pass through the sphincter of Oddi and enter the duodenum.
bile duct(bīl dŭkt)
Any of the ducts conveying bile between the liver and the intestine, including hepatic, cystic, and common bile duct.
Synonym(s): biliary duct.
Synonym(s): biliary duct.
Any of the intercellular passages that convey bile from the liver to the hepatic duct, which joins the duct from the gallbladder (cystic duct) to form the common bile duct (ductus choledochus), and which enters the duodenum about 3 in (7.6 cm) below the pylorus.Synonym: biliary duct See: illustration

bile ductThe narrow tube which carries BILE from the liver to the bowel. The bile collecting tubules in the liver join up to form a main tube called the hepatic duct. Just under the liver, this gives off a branch, the cystic duct, to the gall bladder. The duct continues down, as the ‘common bile duct’ to run into the DUODENUM.
bile ductthe duct through which bile passes from the liver or gall bladder to the duodenum.
1. generally, any of the biliary passages.
2. specifically the terminal segment of the biliary tree extending from the union of the common hepatic duct and cystic duct to the major duodenal papilla. See also bile passages.
bile duct atresia
if it is extensive it causes jaundice and steatorrhea soon after birth. It is observed rarely in kittens and puppies.
bile duct calculi
bile duct canaliculi
formed between adjacent hepatocytes these are the smallest components of the biliary system; they open into biliary ductules.
bile duct carcinoma
see cholangiocellular carcinoma.
bile duct cysts
occur in all species and are probably derived from occluded or atretic embryonic bile ducts.
bile duct ductule
bile duct dyskinesia
a much-argued diagnosis in human medicine. The diagnosis assumes that there is a failure of biliary flow into the intestine for other than physical reasons. The hypothesis likens the problem to that of irritable colon. There is no proof of the existence of the malfunction in humans, much less in animals.
bile duct fibrosis
a common severe lesion, accompanied by mineralization, as a result of infestation by Fasciola hepatica.
bile duct hyperplasia
may be part of a general reaction of the liver but is most important as a purely cholangiolar proliferation, usually as a result of exposure to a poison such as butter yellow.
bile duct inflammation
bile duct obstruction
see biliary obstruction.
bile duct proliferation
see bile duct hyperplasia (above).
bile duct radiology
bile duct rupture/perforation
most ruptures are traumatic and result in leakage of bile into the peritoneal cavity. See also biliary peritonitis.
