The atrium is the receiving chamber of the heart, where blood enters from the veins. The superior vena cava and inferior vena cava both empty into the right atrium, while the pulmonary veins empty into the left atrium. The aorta is the large artery that carries blood away from the heart and is not a receiving region. The capillary bed is where the exchange of nutrients and waste occurs and is not a part of the heart.
