Which heart chamber receives deoxygenated blood?

Explanation:
Deoxygenated blood returns to the heart and first enters the right atrium. This chamber receives blood from the body via the superior and inferior vena cavae (and the coronary sinus) and then passes it to the right ventricle to be sent to the lungs for oxygenation. The aorta is the main artery that carries oxygen-rich blood from the left ventricle to the body, not a chamber. Veins are vessels, not chambers, and the circulatory system refers to the entire network, not a single chamber.
