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.
Yes and no. Veins do contain valves, but arteries do not.
Veins and arteries are considered valves themselves. They are like long tubes and they carry blood from one place to another.
Actually, it is veins that have small valves in them. The valves prevent venous blood from flowing backwards; keeps venous blood moving towards the heart.
yes.
Veins
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 arteries have valves, only veins have valves to stop backflow.
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 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.
Valves function to help keep blood flowing toward the heart. Arteries function to carry blood away from the heart.
Arteries are valve-less vessels, meaning there are no valves.
valves are not present in arteries because in arteries there is high blood pressure
