The biliary tree is a system of vessels that directs these secretions from the liver gallbladder and pancreas through a series of ducts into the duodenum. The right hepatic duct drains the entire right lobe of the liver.

The biliary tree is a series of gastrointestinal ducts allowing newly synthesised bile from the liver to be concentrated and stored in the gallbladder prior to release into the duodenum.

Biliary tree anatomy. The exit hole into the duodenum is called the papilla of vater. Anatomy of the biliary system the biliary system consists of the organs and ducts bile ducts gallbladder and associated structures that are involved in the production and transportation of bile. This distinction is arbitrary because the cystic duct joins at a variable site which must be carefully considered during gallbladder operation.

Intrahepatic bile ducts bile canaliculi unite to form segmental bile ducts which drain each liver segment. The biliary tree also known as the biliary tract or biliary system is comprised of the gallbladder liver and bile ducts. These 2 merge at porta hepatis to form the common hepatic ductchd.

51 parallels the portal venous supply of the liver. Anatomical terminology edit on wikidata the biliary tract biliary tree or biliary system refers to the liver gall bladder and bile ducts and how they work together to make store and secrete bile. It is formed by the union of the anterior right hepatic duct which drains the anterior segments v and viii and the posterior right hepatic duct which drains the posterior segments vi and vii 1.

Bile consists of water electrolytes bile acids cholesterol phospholipids and conjugated bilirubin. The transportation of bile follows this sequence. This includes normal anatomy and variations of the biliary apparatus as well as the arterial supply to the gallbladder.

A look at the basic anatomy is therefore important for biliary and minimally invasive surgeons. There is significant variation in the biliary tree with the classical description below thought to be present in 60 of the population 2. The common bile duct cbd is formed by the junction of the cystic duct with the chd.

Anterior aspect of the biliary anatomy in the hepatic pedicle the common hepatic duct receives the cystic duct and then forms distally to the choledochus. Biliary tree anatomy the biliary tree descends from the canaliculi at the hepatocytes gradually enlarging and merging to the right and left hepatic ducts. By convention the biliary tree is divided into intra and extra hepatic bile ducts 1.

Bile is initially secreted from hepatocytes and drains from both lobes of the liver via canaliculi intralobular ducts and collecting ducts into the left and right hepatic ducts. These structures produce store and release bile to the small intestines where it aids in the digestion of lipids.
