Left Atrium: which statement is correct?

Explanation:
The left atrium’s job is to receive oxygenated blood from the lungs via the pulmonary veins. From the left atrium, blood moves through the mitral valve into the left ventricle, which then pumps to the body via the aorta. So, receiving oxygenated blood is the correct description of the left atrium’s role. The other statements describe functions of other heart chambers: the right ventricle pumps to the lungs; the left ventricle pumps to the body; and the right atrium receives deoxygenated blood from the body.
