Deoxygenated blood from the body returns to the:

Explanation:
Deoxygenated blood from the body returns to the right atrium, which is the heart’s receiving chamber for systemic venous return. Veins from the body, via the superior and inferior vena cavae, drain into this room, then the blood passes to the right ventricle to be sent to the lungs for oxygenation. The left atrium, in contrast, collects oxygenated blood from the lungs, and the aorta carries blood away from the heart to the body. The right ventricle pumps blood to the lungs, not back to the body.
