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.

hey dear....
The first and most important difference between the two is that all arteries carry blood away from the heart, and all veins carry blood to the heart from outlying areas. Most arteries carry oxygenated blood, and most veins carry deoxygenated blood; the pulmonary arteries and veins are the exceptions to this rule.
