What chamber receives oxygenated blood from the pulmonary veins?

Explanation:
Oxygenated blood returning from the lungs via the pulmonary veins enters the heart at the left atrium. This chamber acts as the receiving site for pulmonary venous return and then passes blood through the mitral valve into the left ventricle, which pumps it to the body. In contrast, the right atrium collects deoxygenated blood from the body, the right ventricle sends it to the lungs, and the left ventricle pushes oxygenated blood to the systemic circulation. So, the chamber that receives oxygenated blood from the pulmonary veins is the left atrium.
