part of part of channels_from posterior cardinal vein UBERON:0002065 postcardinal vein AAO:0010511 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 inferior cardinal vein EMAPA:16357 caudal cardinal veins 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] Wikipedia:Posterior_cardinal_vein NCIT:C34257 One of two paired cardinal veins that return blood from the body of the embryo[Kardong]. axial vein UMLS:C0231087 relationship loss: part_of axial vasculature (TAO:0001073)[TAO] relationship loss: part_of cardinal system (TAO:0000096)[TAO] SCTID:308781005 XAO:0000241 BTO:0004386 VHOG:0000111 PCV FMA:70314 Continuation of the caudal vein cranial to the anal pore. The cardinal vein splits into a pair of vessels in the cranial trunk, just caudal to the radix of the aorta. The posterior cardinals each empty into the common cardinal vein.
