The left lobe of the liver is divided by the left hepatic veins and ligamentum teres. Which option states this correctly?

• A. Right hepatic vein
• B. Portal vein
• C. Left hepatic veins and ligamentum teres
• D. Hepatic artery

Answer: (C)

The structures that demarcate the left lobe are the left hepatic veins and the ligamentum teres. The left hepatic veins drain the left portion of the liver into the IVC, creating a venous boundary that helps separate the left lobe from the rest of the liver. The ligamentum teres, a fibrous cord along the edge of the falciform ligament, runs in the fissure on the liver’s surface that marks the left lobe’s border. Together, these landmarks define the division of the left lobe. The right hepatic vein, portal vein, and hepatic artery are not the boundaries that demarcate the left lobe; they relate to drainage and supply but don’t establish that lobar division.
