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

Explanation:
The main idea is where systemic venous return goes into the heart. The inferior vena cava brings deoxygenated blood from the lower body and drains directly into the right atrium. From there, blood moves into the right ventricle and then to the lungs for oxygenation. The left atrium, by contrast, receives oxygenated blood from the lungs, and the pulmonary artery carries blood away from the heart to the lungs, not into the heart. So, the chamber that receives blood from the inferior vena cava is the right atrium.
