Quizplus · Accepted Answer

The right atrium is the chamber of the heart that receives the deoxygenated blood from the systemic system first, via the superior and inferior vena cava. This blood then flows into the right ventricle, which pumps it to the lungs for oxygenation. The left atrium and left ventricle receive oxygenated blood from the lungs, which is then pumped out to the systemic system.
