Preferred Label : posterior cardinal vein;
Uberon definition : One of two paired cardinal veins that return blood from the body of the embryo[Kardong];
Uberon related term : caudal cardinal veins; postcardinal vein; inferior cardinal vein; axial vein; PCV;
Uberon Development note : join with the corresponding right and left cardinal veins to form the left common
cardinal veins, which empty in the sinus venosus. Most of the posterior cardinal veins
regress, 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, renal veins and gonadal veins. The supracardinal veins
form part of the inferior vena cava, the intercostal veins, hemiazygos vein and azygos
vein;
Uberon Homology note : In primitive vertebrates, the basic early embryonic pattern is retained, and blood
from anterior and posterior systemic tissues is returned in anterior and posterior
cardinal veins, both pairs of veins uniting in common cardinal veins near the heart.
In derived vertebrates, the cardinals appear but usually persist only in the embryo,
being functionally replaced by alternative adult vessels, the precava and postcava
(anterior and posterior venae cavae).[well established][VHOG];
