In the heart, which chambers receive blood returning from the body’s veins?

Explanation:
Blood returning from the body goes into the heart’s receiving chambers, the atria. The right atrium collects systemic venous blood via the superior and inferior vena cavae, while the left atrium handles blood from the lungs. The ventricles are the pumping chambers that push blood onward, not where body venous blood first arrives. “Aortic chambers” isn’t a correct term for heart chambers, and auricles are just small extensions of the atria, not separate chambers. So the chambers that receive blood from the body’s veins are the atria.
