No, veins have the valves, arteries don't.
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.
No, they're aren't any valves in the arteries.
All the valves of the heart prevent backflow of the blood through the heart: tricuspid valve, pulmonary valve, mitral valve, and aortic valve. Furthermore, there are one-way valves in the veins that prevent backflow of blood.
Both AV valves, the bicuspid and tricuspid, (separating the ventricles from the atria) prevent blood from flowing back into the atria when the ventricles contract. Both the semilunar valves (separating the arteries from the ventricles) prevent blood from flowing back from the arteries once it has been pumped out of he ventricles, and thus, out of the heart. The difference is that the AV valves are contracted when they are CLOSED, but the semilunar valves are contracted when OPEN. Otherwise, I can't think of another major job besides preventing backflow.
The valves of the heart prevent backflow into the arteries. As a result, the heart can efficiently pump the correct amount of blood to the tissues of the body efficiently and rhythmically. -Cheers The valves of the heart prevent backflow into the arteries.

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.
Only veins contain valves. The valves prevent the backward flow of blood.
Veins carry blood towards the heart, typically carrying deoxygenated blood except for the pulmonary veins. Veins have thinner walls and larger lumens compared to arteries, and contain valves to prevent backflow of blood. Veins are located closer to the surface of the body compared to arteries.
valves are not present in arteries because in arteries there is high blood pressure
They have very long neck which the pulses in the arteries are not strong enough to push the blood up to the brain. The "VALVES" prevent the back flow of blood.........
cause their prevent bac flow
Veins contain valves to prevent backflow of blood. The blood pressure in the veins is lower than in arteries because it is farther from the heart. Additionally, it is often fighting against gravity, so the prevention of backflow becomes essential.
No arteries have valves, only veins have valves to stop backflow.
No, only venous vessels have valves. Valves in veins help prevent the backflow of blood and aid in promoting blood flow back to the heart. Arterial vessels do not have valves because blood in arteries is under higher pressure and flows away from the heart.
