biliary tract the organs, ducts, and other structures that participate in secretion (the liver), storage (the gallbladder), and delivery (hepatic and bile ducts) of bile into the duodenum. See illustration.

biliary tract

Etymology: L, bilis, bile, tractus
the pathway for bile flow from the canaliculi in the liver to the opening of the bile duct into the duodenum.

biliary tract

The biliary plumbing system, which consists of the gallbladder, intrahepatic bile ducts, cystic duct—gallbladder to common bile duct—and common bile duct—liver and gallbladder to small intestine. Biliary tract obstruction usually leads to obstructive jaundice.

BILIARY TRACT (IN RELATION TO LIVER, PANCREAS, AND DUODENUM)

biliary tract

The organs and ducts through which bile travels on its way to the duodenum. These are the bile canaliculi, right and left hepatic ducts, common hepatic duct, gallbladder, cystic duct, bile duct, and hepatopancreatic ampulla.
See: illustration; bile ducts; gallbladder; liver
See also: tract

biliary

pertaining to the bile, to the bile ducts, or to the gallbladder. See also bile duct.

biliary excretion
removal in the bile of substances including drugs, toxins, hormones or pigments, or their breakdown products. These are delivered to the duodenum and removed in the feces.
biliary fever
biliary fibrosis
one of the three forms of hepatic fibrosis; largely confined to the portal triads; see also bile duct fibrosis.
biliary infarct
areas of hepatic fibrosis that physically resemble vascular infarcts but are related to damaged bile ducts.
interlobular biliary duct
biliary obstruction
obstruction of biliary ducts may be intra- or extrahepatic, and intraluminal (calculi) or by external compression by tumor mass or cicatricial contraction, or more commonly in food animals by migrating ascarid larvae in the bile ducts or by cholangitis caused by Fasciola hepatica or Dichrocoelium dendriticum. Jaundice is the outstanding clinical sign of the condition. See also cholestasis.
biliary salts
see bile salt.
biliary stones
biliary tract
the organs, ducts, etc., participating in secretion (the liver), storage (the gallbladder, if present), and delivery (hepatic and bile ducts) of bile into the duodenum.
