Pulmonary Arteries

The pulmonary arteries are responsible for carrying deoxygenated blood from the right side of the heart to the lungs. This deoxygenated blood gets oxygenated in the lungs and returns to the heart via the pulmonary veins. This process is essential for life because our bodies require a continuous supply of oxygen to function properly. Pulmonary arteries can be affected by various diseases including pulmonary hypertension, a condition in which the pulmonary arteries become narrowed, restricting the flow of oxygenated blood to the lungs. The diagnosis, management and treatment of pulmonary artery diseases are therefore crucial to maintaining a healthy respiratory system.
