channels_from vasculature of head anterior cardinal vein ACV precardinal vein One of the the two paired cardinal veins draining the cephalic part of the body. UBERON:0009770 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] EHDAA:1312 NCIT:C34108 UBERON:0003087 superior cardinal vein XAO:0000383 BTO:0004387 rostral cardinal veins EMAPA:16241 The anterior cardinal vein returns blood from the dorsal head and drains into the duct of Cuvier via the pronephric sinus.[AAO] contribute to the formation of the internal jugular veins and together with the common cardinal vein form the superior vena cava.
