Answer» Arteries carry blood from jeart and veins carry blood to the heart Artery carry oxygenated blood except the pulmonary arteries. Artery have thick and elastic wall. In arteries there is no present valve. While i veins carry deoxygenated blood except pulmonary veins. It have less thick and elastic wall as compared to arteries. Valve is present in vein. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries. Because the pressure within them is low, veins have valves inside them to keep blood flowing only one way. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues. |
