Biliary Tree

The Biliary Tree (pronounced: bil-ee-air-ee tree) is a system of vessels that conducts bile from the liver and gallbladder to the duodenum. The term "biliary tree" is derived from the Latin word "bilis", which means bile, and the Greek word "arbor", which means tree.

Anatomy

The biliary tree begins with the bile ducts within the liver, which join to form the hepatic ducts. The hepatic ducts merge to form the common hepatic duct, which joins with the cystic duct from the gallbladder to form the common bile duct. The common bile duct then empties into the duodenum, the first section of the small intestine.

Function

The primary function of the biliary tree is to transport bile, a fluid produced by the liver that aids in the digestion of fats. Bile is stored in the gallbladder and released into the duodenum during digestion.
