The superior vena cava is located above the heart, carrying deoxygenated blood from the upper body to the heart. The inferior vena cava is situated below the heart, transporting deoxygenated blood from the lower body to the heart.
The aorta has significantly thicker walls than the superior and inferior venae cavae as the aorta is an artery that must respond to significant intraluminal pressures whereas the venae cavae are veins that have minimal intraluminal pressure.
The largest veins are the venae cavae that return deoxygenated blood from the body into the heart.
