The liver is the largest viscus in our body. It is made up of cells called hepatocytes, among which the hepatic sinusoids (where blood circulates), and the bile caniculi (where bile circulates) are found. The liver fulfills four main functions: secretion, metabolism, disintoxication, and storage. The biliary system. Bile originates in the cells of the liver, or hepatocytes. It is carried from the liver to the digestive tract through a group of ducts and canaliculi called biliary system. The gallbladder, where bile is stored, is 10 to 12 cm long. Bile is then drained into the digestive tract via the cystic duct. The choledoch duct is the one that starts at the joint of the hepatic duct and the cystic duct, in the lower face of the liver.
