to maintain blood flow and pressure
Veins have valves so the blood dosent backflow
So that the blood dosen't flow the wrong way
Valves cause our blood to flow in one direction, thus preventing regurgitation of blood.
all veins contain valves
Only veins contain valves. The valves prevent the backward flow of blood.
Veins
Valves are in the veins.
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
veins have valves. y
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.
In the large veins. Because in the large veins the blood must fight the gravity, the blood is flowing up, there are valves in them to prevent the blood to fall down again.
No, veins have the valves, arteries don't.
