No. It is the largest artery in the body.
The one going TO the heart from the body probably. I think the pulmonary vein which goes to the heart from the lungs at the heart is probably the same size due to the amount of blood that flows to the heart.
The largest vein in the human body is the inferior vena cava, the vein that returns blood from the lower half of the body back to the heart.
In your heart
I believe the largest artery is the aorta and the largest vein is the superior vena cava. I think inferior vena cava is also one of the largest vein.
The aorta is the largest artery.
the great arterial trunk that carries blood from the heart to be distributed by branch arteries through the body .(noun)
Aorta
The longest vein in the human body would be the saphenous vein.
aorta
The aorta and the pulmonary vein are both major blood vessels in the circulatory system, but they serve different functions. The aorta is the largest artery, carrying oxygen-rich blood from the left ventricle of the heart to the rest of the body. In contrast, the pulmonary vein transports oxygenated blood from the lungs to the left atrium of the heart. Additionally, the aorta is part of the systemic circulation, while the pulmonary vein is part of the pulmonary circulation.
Vena cava. Whereas the aorta is the body's largest artery, the vena cava is the biggest vein.
Veins, the largest vein cavae, are even largest in Diametre than Aorta arteri
