3.The largest known artery is the aorta.	3. The largest known veins are the inferior vena cava (carrying deoxygenated blood from the lower body) and the superior vena cava (carrying deoxygenated blood from the lower body).
4. Generally, arteries carry oxygenated blood, but the pulmonary artery is an exception that carries deoxygenated blood from the right ventricle to the lungs.	4. Similarly, veins carry deoxygenated blood, but the pulmonary vein is an exception that carries oxygenated blood from the lungs ventricle to the right atrium of the heart.
5.The walls of the arteries are thicker in comparison to veins as the blood pressure inside the arteries is more.	5. The walls of the veins are less thicker than arteries.
