Which of the following forms the caudal border of the left portal vein?
A. Ligamentum venosum
B. Hepatoduodenal ligament
C. Main lobar fissure
D. Coronary ligament
E. Ligamentum teres - ANSE. Ligamentum teres.
What ligament divides the left lobe of the liver into medial and lateral segments?

D. The portal veins are accompanied by branches of the biliary tree and hepatic artery.
E. The portal veins normally exhibit a triphasic flow pattern. - ANSD. The portal veins are
accompanied by branches of the biliary tree and hepatic artery.
