Detailed explanation-1: -Your inferior vena cava, your body’s largest vein, carries oxygen-depleted blood back to your heart from the lower part of your body (below your diaphragm). Your superior vena cava, your second biggest vein, brings oxygen-poor blood from your upper body to your heart. Think of it like a bus line.
Detailed explanation-2: -The inferior vena cava returns de-oxygenated blood from the lower body regions (legs, back, abdomen and pelvis) to the right atrium. The ventricles of the heart function to pump blood to the entire body. Right ventricle: Receives blood from the right atrium and pumps it to the main pulmonary artery.
Detailed explanation-3: -The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.
