Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
Arteries carry blood with oxygen to the heart. Veins carry blood full of carbon dioxide to the lungs. Arteries have a thick wall. Veins have a thin wall. Arteries have no valves. Veins have valves.
Veins, arteries or valves
No, veins have the valves, arteries don't.
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Arteries carry blood away from the heart. Veins return blood to the heart.
No arteries do not contain valves since there is enough pressure from the heart to force blood through these vessels without significant backflow between contractions.
veins have valves because they bring blood from the bottom half of your body and valves stop the back flow of blood since the veins work against gravity.
