    In a typical case, there are two pulmonary veins that travel to each lung. The pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the heart. Each lung receives blood from two pulmonary veins, one from the superior lobe and one from the inferior lobe. This allows for efficient oxygenation of the blood and transportation of oxygen to the rest of the body.
