external definition

Bilaterally paired longitudinal vein; the anterior cardinal returns blood from the head, and the posterior cardinal returns it from the trunk; these two vessels join together on each side as the common cardinal vein (duct of Cuvier; misnamed the vitelline vein) that leads across the yolk cell to the heart's sinus venosus. Kimmel et al, 1995.[TAO]

homology notes

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]
