quadrate lobe of liver
The liver is divided into a large right lobe and a small left lobe. The division is made by the attachment of the falciform ligament. The right lobe is further divided into a quadrate lobe and a caudate lobe by the presence of the gallbladder and the inferior vena cava. The quadrate and caudate lobes are functional parts of the liver. The right and left branches of the hepatic artery and portal vein, as well as the right and left hepatic ducts are distributed to the right and left lobes respectively. The two overlap very little. The porta hepatis is found on the inner surface and lies between the caudate lobe and the quadrate lobe. In this lies the right and left hepatic ducts, the two branches of the hepatic artery, the portal vein and lymph nodes. There are also a few hepatic lymph nodes, which drain the liver and gallbladder. The hepatic vessels then run to the celiac lymph nodes.
