Pulmonary Arteries

Pulmonary arterial hypertension. Pulmonary arterial hypertension (PAH) is a rare form of high blood pressure. It occurs in the pulmonary arteries, which flow from your heart and throughout your lungs. Constricted and narrowed arteries prevent your heart from pumping adequate blood.

How the Main Pulmonary Artery Delivers Blood to the Lungs. The right pulmonary artery carries blood to the right lung while the left pulmonary artery carries it to the left lung. The pulmonary arteries are unique in that unlike most arteries which carry oxygenated blood to other parts of the body, the pulmonary arteries carry de-oxygenated blood…

The specific role of the pulmonary arteries is to carry blood that’s low in oxygen and high in carbon dioxide waste to the pulmonary capillaries of the lungs, where this exchange takes place. When the blood is enriched with oxygen and cleared of carbon dioxide waste, it flows back through your pulmonary veins to your heart’s right ventricle.
