No, the valves that prevent backflow of blood are one-way valves.
Valves prevent the backflow of blood
valves prevent the backflow of blood.
Only veins contain valves. The valves prevent the backward flow of blood.
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.
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.

In the bodies blood system, they prevent back flow of the blood (one way valves) .
One-way valves prevent the back flow of bloodThere are tiny one way valves throughout a vein. These stop blood from flowing backwards. Interestingly, when these valves in veins in the legs malfunction, the result are varicose veins.
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.
Valves allow forward blood flow. Valves prevent the back flow of the blood. You have beautiful small muscles in your ventricles. They are called as papillary muscles. They are attached to the bicuspid and tricuspid valves and simultaneously contract, during the contractions of the ventricles, to prevent the collapse of the cusps of the valves. The aortic and pulmonary valves prevent the back flow by there anatomical advantage. This way, the valves ensure the continuous unidirectional flow of blood.
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
