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.
The pulmonary arteries carry blood to smaller arterioles and on to the vast capillary beds of the lungs where carbon dioxide is released and oxygen is obtained from the air in the alveoli of the lungs. These capillaries converge into larger venules, which further converge to form the left and right pulmonary veins.he pulmonary arteries and pulmonary veins provide vital but short distance blood flow between the heart and the lungs. Exiting the heart from the right ventricle, deoxygenated blood flows into the large pulmonary trunk before splitting at the left and right pulmonary arteries.
