Hepatic veins

Portal veins.

Portal vein, hepatic artery, bile duct.

Imaginary line from GB to IVC, middle hepatic vain is landmark for it.

Right and left lobes of the liver.

Right anterior segment from left medial segment.

Coronal division of the right lobe of the liver, dividing right lobe to anterior and posterior, right hepatic vein is landmark for right Intersegmental fissure.

Sagittal division of the left lobe of the liver, divides the left lobe to medial and lateral, the left hepatic vein, ligamentum teres, falciform ligament, assending segment of the left portal vein are landmarks.

Remnant of ductus venosus, conducts blood from the left portal vein to IVC, separates medial segment of left lobe from caudate lobe.

Posterior portion of liver that is not covered by peritoneum.

Reflection of parietal peritoneum onto liver surface, visceral peritoneum.
