Common hepatic duct

*Common hepatic duct (ductus hepaticus communis)* is a narrow channel through which bile flows from the hepatic lobes into the cavity of the gallbladder. It enters the lower surface of the right lobe of the liver and enters the hepatoduodenal ligament, then through the portal of the liver it enters the abdominal cavity, where it goes to the left and passes into the cystic process of the biliary tree along with the cystic artery. The hepatic ducts are straight and short in newborns and children under 2-3 years of age, then they acquire an S-shape, increasing in length.

Each liver lobule begins with capillaries, which begin from the so-called hepatic acini. One hepatic acini contains approximately four hepatocytes. The hepatic acinar zone consists of several triads - hepatocytes surrounding the hepatoportal venous vein and the hepatic artery, which emerges from this triad. The bile canaliculus, which collects from one triad, flows to the adjacent triad in the opposite lobe of the liver. Thus, thanks to the mass of united triads of the systemic circulation, the bile duct enters from each lobe. The hepatocytes that make up the acin are the primary derivatives of hematopoietic blood cells. Hematopoietic cells first mature in the so-called yolk sac in the abdominal cavity. The constituent regions of the liver receive this yolk sac and are saturated with bile production during fetal development. At first the holes

Hepatic duct The hepatic duct is a large (venous) intrahepatic vessel that collects and drains filtered blood into the inferior vena cava. It is one of 3 hepatic channels - bile ducts. Distributes blood along the branches of the portal vein into the sinusoids, this ensures increased blood flow in the liver, thanks to which the cells are supplied with oxygen and nutrients. The main part of the hepatic duct is common to all lobes of the liver. It continues after the underlying connective tissue and expands towards the end to form the vesical gallbladder. In some cases, it may be absent in newborns. Next, the blood flows from the hepatic canal to the hepatic vein, and then to the portal or inferior vena cava system. The hepatic canal extends to the anterior part of the left lateral surface of the liver lobe and to the posterior surface of the right lobe. It extends from about 6 to 8 cm (about 2.5 to 3 inches) in the right half and 3 to 5 cm (about
