What chamber of the heart receives oxygenated blood from the lungs?

Oxygenated blood from the lungs returns to the heart and first enters the left atrium through the pulmonary veins. From there, blood moves to the left ventricle via the mitral valve, where it’s pumped out to the body. The right atrium, by comparison, collects deoxygenated blood from the body via the superior and inferior vena cava, and the right ventricle sends that blood to the lungs. The essential idea is that the lungs’ oxygenated blood ends up in the left atrium.
