The 3 major differences between arteries and veins are...?

-Arteries carry blood away from the heart and and veins carry blood towards the heart

• Arteries have thick walls with muscle tissue, veins have thinner walls and use valves

• arteries carry oxygenated blood and veins carry deoxygenated blood.
