Which chamber receives oxygenated blood from the lungs via the pulmonary veins?

Explanation:
Oxygenated blood from the lungs returns to the heart through the pulmonary veins and enters the left atrium. The left atrium is the chamber that receives this oxygen-rich blood, which then passes through the mitral valve into the left ventricle to be pumped to the body. The other chambers have different roles: the right atrium collects deoxygenated blood from the body via the superior and inferior vena cava; the right ventricle sends deoxygenated blood to the lungs; the left ventricle delivers oxygenated blood to the systemic circulation. Therefore, the left atrium is the chamber that receives oxygenated blood from the lungs via the pulmonary veins.
