What does the pulmonary artery do?
Moves blood from the heart to the lungs.
in the pulmonary loop, the heart pumps blood from the heart through pulmonary artery that is low in oxygen and high in carbon dioxide concentration, to the lungs. Gas exchange occurs around alveoli of lungs and oxygenated blood returns to the heart via the pulmonary veins.
Pulmonary artery arises from right ventricle, divides in two branches to send blood in lungs of both sides.
arteries are generally thicker walled an able to withstand greater pressure (coming out of ventricles), whereas veins are typically thinner walled and don't experience as much pressure as it returns to atrium.
