Which side of the heart pumps deoxygenated blood to the lungs?

Explanation:
The heart has two separate circuits: the right side handles blood coming back from the body and sends it to the lungs for oxygen, while the left side handles oxygenated blood to the rest of the body. Deoxygenated blood returns to the heart and is routed to the lungs by the right side. Blood from the body returns to the right atrium, moves to the right ventricle, which then pumps it into the pulmonary artery toward the lungs for gas exchange. After oxygenation, the blood returns to the left atrium and moves to the left ventricle to be circulated to the body. So, deoxygenated blood is driven toward the lungs by the right side of the heart.
