Firstly the direction of blood flow for arteries is downward from the heart to the body tissues. The veins carry blood from the body tissues to the heart upward. Next is that the arteries are in charge of transporting oxygenated blood away from the heart to various organs. On the other hand, Veins transport deoxygenated blood from multiple organs of the body to the heart for oxygenation. Lastly the arteries locates deeper within your body and have thick elastic muscle walls. Veins have thin, non-elastic, less muscular walls, and most of them are closer to your skin’s surface.
