The liver is divided into right and left lobes by the falciform ligament anterosuperiorly and the fissure for the ligamentum venosum and ligamentum teres on the visceral surface.  (Fig. 4.104). The right lobe of the liver is the largest lobe, whereas the left lobe of the liver is smaller. The quadrate and caudate lobes are described as arising from the right lobe of the liver but functionally are distinct.
