Falciform ligament
- B.
Ligamentum venosum
- C.
Main lobar fissure
Correct Answer
B. Ligamentum venosumExplanation
The left lobe is separated from the caudate lobe by the Ligamentum venosum. The Ligamentum venosum is a fibrous band of tissue that runs between the left lobe of the liver and the caudate lobe. It is a remnant of the fetal circulation, specifically the ductus venosus, which shunted blood away from the liver during fetal development. As the fetus grows and the circulatory system changes, the ductus venosus closes off and becomes the Ligamentum venosum. This ligament acts as a barrier between the left and caudate lobes, helping to maintain the structural integrity of the liver.Rate this question:
