Detailed explanation-1: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
Detailed explanation-2: -Understanding Circulatory Vessels : Example Question #1 Arteries generally carry oxygenated blood to deliver oxygen to organs, and veins generally carry deoxygenated blood back to the heart for re-oxygenation. The singular exceptions are the pulmonary arteries and pulmonary veins.
Detailed explanation-3: -The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Systemic veins carry low-oxygen blood from the body to the right atrium of the heart.
