Which blood vessel is involved in transporting deoxygenated blood to the lungs?

The pulmonary artery is responsible for transporting deoxygenated blood from the heart to the lungs. Once the blood returns to the heart from the body, it enters the right atrium, moves to the right ventricle, and is then pumped into the pulmonary artery. This artery begins the process of sending the blood to the lungs where it will receive oxygen and release carbon dioxide.

In contrast, other blood vessels mentioned are involved in different functions. The aorta carries oxygenated blood away from the heart to the rest of the body. The pulmonary vein, on the other hand, transports oxygenated blood back from the lungs to the heart. Finally, the coronary artery supplies oxygenated blood directly to the heart muscle itself. Each of these vessels has a specific role in the circulatory system, highlighting the unique function of the pulmonary artery in gas exchange.
