The left portal vein divides into which two branches?

Explanation:
The left portal vein divides into two branches: a medial branch and a lateral branch. This split aligns with how the left liver segments are supplied: the medial branch covers the medial portion of the left lobe (including segment IV), while the lateral branch supplies the lateral left segments (typically II and III). The other pairings (anterior/posterior, superior/inferior, or anterior and lateral) do not describe the typical division pattern of the left portal vein, which is specifically medial and lateral.
