Anatomical terminology [edit on Wikidata]

The posterior cardinal veins or postcardinal veins join with the corresponding right and left cardinal veins to form the left common cardinal veins, which empty in the sinus venosus. In the development of a human embryo, most of the posterior cardinal veins regress, and what remains of them forms the renal segment of the inferior vena cava and the common iliac veins. Later in the development stages, the posterior cardinal veins are replaced by the subcardinal and supracardinal veins. The subcardinal veins form part of the inferior vena cava, the renal veins and the gonadal veins. The supracardinal veins form part of the inferior vena cava, the intercostal veins, the hemiazygos vein and the azygos vein.^[1]
