Which chamber receives oxygenated blood from the lungs?

Explanation:
The function being tested is how blood that has been oxygenated in the lungs returns to the heart. Oxygen-rich blood from the lungs returns via the pulmonary veins and enters the heart into the left atrium. The left atrium serves as the receiving chamber for this oxygenated blood before it moves to the left ventricle to be pumped out to the body. In contrast, the right atrium handles deoxygenated blood from the body, the right ventricle sends that deoxygenated blood to the lungs, and the left ventricle distributes oxygenated blood to the systemic circulation.
