Veins take blood to the heart, while arteries take blood away from the heart. Also, veins have valves that don't allow backflow because their wall contains almost no smooth muscle to pump the blood - they cannot constrict and dilate on their own. Veins rely on the body's muscular movement to move the blood contained in them. Arteries, however, can constrict or dilate to diver blood flow to different parts of the body and to keep blood pressure relatively constant. They have a large smooth muscle component in their walls.

What would happen if your body only had viens and no arteries?
Viens bring deoxygenated (no oxygen) blood back to the heart. Arteries bring oxygenated (with oxygen) to tissues, muscles, etc. throughout the body. If there are no arteries, tissures, muscles, etc. couldn't get oxygen or nutrients, and therefore, couldn't fuction. The result is immediate death.
How blood passes to all parts of the body?
