Veins contain valves preventing blood from circulating backwards.
valves in the veins
The flap of tissue that prevents blood from flowing backward is called a valve. Valves are found in veins and in the heart to ensure that blood flows in one direction and does not pool or backflow.
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
Blood is a constant whereabout in our bodies. As of such a frequent heartbeat exists within our system. Which causes the blood within our bodies to flow forward, in lamense terms it produces a very large push for the blood to distribute it's nutrients throughout the body and back within our heart and out again. This constant push is what prevents blood from flowing backwards in your veins.

valves
Veins, arteries, capilarries?
When one of the heart ventricles (the lower chambers) contracts, it pushes blood out of the heart. A valve prevents this blood from going backward into the atrium, which has completed its contraction and is now relaxed and being filled with blood from the veins.
blood flows into the veins quiet slowly as they are much wider compared to the flow of blood in the arteries which are rather narrow.because of the low pressure of blood on the flow inside the veins there are great possibilities that the blood is likely to flow backwards which may cause complications in the flow of blood.to prevent this from happening the veins contain valves that stop the back flow of blood
Valves in the veins prevent the blood from flowing backward or from pooling.
yes.. yes they do :)
Valves in the veins prevent the backflow of blood by closing to keep the blood moving in one direction towards the heart.
