Pulmonary Artery & Vein


Pulmonary Artery

The pulmonary artery carries deoxygenated blood from the heart to the lungs. It is one of the only arteries that carry deoxygenated blood. It is relatively short and wide in size and shape. It begins from the bottom of the right ventricle of the heart. And then separates into the right and left pulmonary arteries, which lead to the respective lungs (the right and the left).

Pulmonary Vein

The pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart. It is one of the few veins which carry oxygenated blood. There are four pulmonary veins in the human body, two veins arising from each lung. Each pulmonary vein is linked to a network of capillaries in the alveoli of each lung.
