Always remember Artery carries blood away from the Heart, and Vein carries blood towards the heart, no matter it be oxygenated or deoxygenated blood! Nextly, Arteries are deep seated into our body, we cant see them directly, whereas Veins are superficial, you can notice those blue lines on hands especially! Also, Arteries do not have valves, because blood in it flows by the pressure of heart whereas, Veins have Valves, so as to prevent the back flow of Blood into the tissues!
Thats all for now!
