Pulmonary Vein Anatomy

This differentiates the pulmonary veins from other veins in the body which are used to carry deoxygenated blood from the rest of the body back to the heart. Anatomy of the pulmonary veins.

Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart.

Pulmonary vein anatomy. The four pulmonary veins play an important role in the pulmonary circulation by receiving oxygenated blood from the heart and delivering it to the left atrium where it can then enter the left ventricle to be circulated throughout the body. The largest pulmonary veins are the four main pulmonary veins two from each lung that drain into the left atrium of the heart. The distal segments of the pulmonary veins are intrapericardial.

Veins are the blood vessels that carry blood to the heart. Most individuals have four pulmonary veins two on the left and two on the right the inferior and the superior one but there are also different anatomical variations. Typically there are four pulmonary veins with superior and inferior pulmonary veins on either side draining into the left atrium.

Knowledge of the size and morphology of the pulmonary veins and their ostia is important because considerable differences may be seen among patients. The pulmonary veins are covered by a short 9 mm myocardial layer which is often the electrical focus of atrial fibrillation with the left superior pulmonary vein being the foci for almost half of cases. The ostia of the inferior pulmonary veins are more dorsal and medial than those of the superior pulmonary veins 2 and the ostia of the left pulmonary veins are located higher than those of the right pulmonary veins 5.

The pulmonary capillaries surround and embrace millions of tiny air sacs called alveoli in your lungs. Just like the other veins in your body your pulmonary veins arise from a network of capillaries. However the capillaries that give rise to the pulmonary veins differ from capillaries elsewhere in your body.

The pulmonary vein is unique in that it is the only vein that carries oxygenated blood. The pulmonary veins are part of the pulmonary circulation. These abnormal foci can be treated with rfa.

The pulmonary veins pvs are large blood vessels that carry oxygenated blood from the lungs and drain into the left atrium la of the heart. The left ventricle the left inferior portion of the heart has walls three times as thick as those of the right ventricle. In reference to the heart the right pulmonary veins pass behind the right atrium and superior vena cava return and the left pulmonary veins pass in front of the descending thoracic aorta.

Left atrium receives the four pulmonary veins which bring oxygenated blood from the lungs. Blood flows from the left atrium into the left ventricle. Finally the bronchus is located behind the pulmonary artery.

The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart.
