The aorta has thicker walls as it is an artery not vein.
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.
superior vena cava
Vena cava. Whereas the aorta is the body's largest artery, the vena cava is the biggest vein.
The posterior vena cava and the aorta work together to move blood to and from the lower half of the body.
The vena cavae, which returns blood from the bottom half of your body back to your heart.
The superior vena cava, inferior vena cava aorta and other major blood vessles
That is correct, the Vena Cava is the "mothership" of your body's vein system, and the main artery is the Aorta. The Vena Cava and the Aorta stem directly from the heart and branch into the various paths of blood vessels.
The inferior vena cava
The largest blood vessels in the human body are the aorta and the vena cava. The aorta is the main artery that carries oxygenated blood from the heart to the body, while the vena cava comprises two large veins (superior and inferior) that return deoxygenated blood from the body back to the heart. Both vessels play critical roles in the circulatory system, but they transport blood in opposite directions and differ in structure; the aorta has thicker, more muscular walls to withstand high pressure, whereas the vena cava has thinner walls due to lower pressure.
