Biliary System Of Human Body Anatomy and Functions. Anatomy of the biliary system Biliary system of human being The biliary track (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 . Bile consists of water , electrolytes, bile acids,cholesterol, phospolipids and conjugated bilirubin.Some components are synthesised by hepatocytes (liver cells), the rest are extracted from blood by the liver. 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. The transportation of bile follows this sequence: When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. These ducts ultimately drain into the common hepatic duct. The common hepatic duct then joins with the cystic duct from the gallbladder to form the
