hemiazygous and azygous vein.
Its portocaval anastomosis...
portal v. connects with the vena caval drainage at 1) esophagus, 2) rectum, 3) umbilicus, 4) retroperitoneal gut structures; portal v. courses between two capillary beds (gut and liver)

In the liver this vein ramifies like an artery and ends in capillary-like vessels termed sinusoids, from which the blood is conveyed to the inferior vena cava by the hepatic veins.
