Detailed explanation-1: -Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava while deoxygenated blood from the upper body is delivered to the heart via the superior vena cava . Both the superior vena cava and inferior vena cava empty blood into the right atrium.
Detailed explanation-2: -The IVC enters the right atrium of the heart after coursing through the diaphragm, entering the posterior inferior aspect of the atrium. The IVC enters the right atrium inferior to the entrance of the superior vena cava (SVC).
Detailed explanation-3: -The vena cavae are the terminal parts of the extensive venous networks throughout the periphery returning deoxygenated blood to the heart. The inferior vena cava carries deoxygenated blood from the tissues below the diaphragm.
