The Right Pulmonary Artery is a major blood vessel that carries deoxygenated blood from the heart's right ventricle to the right lung. It is part of the pulmonary circulation system, which is responsible for transporting blood to the lungs for oxygenation. Once in the right lung, the blood passes through smaller branches of the artery, allowing for gas exchange in the alveoli. This process is essential for delivering oxygen to the body and removing carbon dioxide. The Right Pulmonary Artery is crucial for maintaining proper respiratory function and overall cardiovascular health.
