They are the only arteries (other than umbilical arteries in the fetus) that carry deoxygenated blood.. BTO:0000778 NCIT:C12774 Major artery which supplies blood to the lungs.[AAO] galen:PulmonaryArtery In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide - approximately 5 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung[WP] CALOHA:TS-0839 GAID:505 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] One of two arteries, leaving from the heart, the left one supplying the left lung and the right one supplying the right lung.
