Answer» The arteries and veins differ each other in the following ways:(1) all arteries except Pulmonary artery carries oxygenated blood whereas all vein except Pulmonary vein carries deoxygenated blood.(2) the internal wall of arteries are thicker and stronger than that of veins as the pressure of blood is higher in arteries as compared to veins. Arteries carry oxygenated blood except pulmonary artery . They have ability to dilate . They do not have valves . For eg.aorta etc..Veins carry deoygenated blood except pulmonary vein. They do not dilate . They have valves . For eg.venecava(superior and inferior). |
