Which chamber receives deoxygenated blood from the body?

Explanation:
Deoxygenated blood from the body returns to the heart and is collected by the right atrium. Blood from the upper body travels through the superior vena cava and from the lower body through the inferior vena cava (with the coronary sinus bringing blood from the heart muscle) into this chamber. From the right atrium, blood moves through the tricuspid valve into the right ventricle, which then pumps it to the lungs via the pulmonary artery for oxygenation. In contrast, oxygenated blood from the lungs returns to the left atrium, moves to the left ventricle, and is distributed to the body. This pathway shows why the right atrium receives deoxygenated blood from the body.
