Write at least three difference between arteryand vein with diagram​

Bonjour,

1. Arteries carry blood from the heart to the rest of the body, whereas veins carry blood from the rest of the body back to the heart.

2. Almost all arteries carry oxygenated blood and almost all veins carry deoxygenated blood.

3. Arteries have a thick elastic muscle layer, whereas the muscle layer for veins is much thinner.

Difference Between Artery and Vein Artery 1. Vessels which carry blood from the heart to various body parts  2. Arteries carry oxygenated blood from the heart except pulmonary artery  3. Arteries have thick elastic muscular walls  4. Valves are absent  5. Blood flows under high pressure  Vein  1. Vessels which carry blood from the various body parts to the heart  2. Veins carry deoxygenated blood from the various body parts except pulmonary vein  3. Veins have thin non elastic walls  4. Valves are present to prevent the backward flow of blood  5. Blood flows under low pressure
