What circulatory element transports deoxygenated blood from the heart to the lungs?

The pulmonary artery is responsible for transporting deoxygenated blood from the heart to the lungs. This process is crucial for oxygenation; when the heart pumps, the right ventricle sends deoxygenated blood into the pulmonary arteries. These arteries then carry the blood to the lungs, where carbon dioxide is exchanged for oxygen.

In this circulatory process, the pulmonary artery is distinct from the aorta, which carries oxygenated blood from the heart to the rest of the body. The pulmonary vein, on the other hand, carries oxygenated blood back from the lungs to the heart. The superior vena cava brings deoxygenated blood from the upper body back to the heart, specifically into the right atrium, but it does not transport it to the lungs. Thus, the role of the pulmonary artery in delivering deoxygenated blood to the lungs for re-oxygenation is essential for maintaining efficient gas exchange and overall bodily function.
