The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.he pulmonary arteries originate from the truncus arteriosus and the sixth pharyngeal arch. The truncus arteriosis is a structure that forms during the development of the heart as a successor to the conus arteriosus.
Blood passes through the capillaries. The pulmonary artery carries blood containing carbon dioxide to the air sacs, where the gas moves from the blood to the air, according to the NHLBI. Oxygenated blood goes to the heart through the pulmonary vein, and the heart pumps it throughout the body. The diaphragm, a dome-shaped muscle at the bottom of the lungs, controls breathing and separates the chest cavity from the abdominal cavity, the American Lung Association noted.
