On the other hand, in the sister clade of the actinopterygians, the sarcopterygians, the gill circulation is supplemented with lung ventilation. As a result, the pulmonary artery and vein and a functional ductus arteriosus arose as a major evolutionary innovation from the sixth arch, giving the organism a flexible shunt to balance blood supply to and from gills and lungs according to environmental conditions.[well established][VHOG] MESH:D011667 XAO:0000394 FMA:66643 uberon Wikipedia:Pulmonary_vein EMAPA:18645 SCTID:430160002 VHOG:0001133 BTO:0001799 UMLS:C0034090 the veins that return oxygenated blood from the lungs to the left atrium of the heart NCIT:C12776 EHDAA2:0001579 pulmonary venous tree organ part CALOHA:TS-0840 MA:0002206 One of two pairs of large vessels that return oxygenated blood from each lung to the left atrium of the heart.
