The figure below shows the gross anatomy of the liver.
           Visual examination reveals that the liver is separated into two lobes,
           the right and the left (Figure a), separated by the falciform ligament.
           The right lobe is about six times the size of the left and contains two
           lesser lobes (Figure b).
 

         The porta hepatis is the entry way for supplying blood vessels (the
      portal vein and the hepatic artery) as well as the exit site of ducts that
      drain bile formed in the liver. Bile leaves the liver via the right and left
      hepatic ducts, which then unite to form the common hepatic duct. The
      common hepatic duct in turn joins with the cystic duct from the
      gallbladder to form the common bile duct. Bile is stored in the
      gallbladder (a pear-shaped bag), and then it flows through the cystic
      duct into the common bile duct and empties into the intestine.
