EMAPA:16356 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, also known as the duct of Cuvier that leads to the heart's sinus venosus.[AAO] Cuvierian duct BTO:0004388 Wikipedia:Common_cardinal_veins EHDAA:1314 ZFA:0000186 UBERON:0002064 Paired in gnathostomes; with only a vestige of the right duct in the adult hagfish (21) and the left duct atrophying at metamorphosis in the lamprey (22)[PMID:20959416, S1] future coronary sinus NCIT:C34130 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] TAO:0000186 duct of Cuvier 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.
