The inferior vena cava delivers deoxygenated blood from the lower body to which chamber of the heart?

Explanation:
Deoxygenated blood returning from the lower body must first enter the heart’s right side to begin the journey to the lungs. The inferior vena cava delivers this blood into the right atrium, which serves as the receiving chamber for all systemic venous return. From there, blood moves into the right ventricle and is pumped to the lungs via the pulmonary artery for oxygenation. The left atrium, by contrast, collects oxygenated blood from the lungs, and the right ventricle’s role is to push blood onward to the lungs, not to receive it from the systemic veins. The pulmonary artery carries blood away from the heart to the lungs.
