That is so true! In fact it is the function of the heart valves.
Yes.
Blood veins have valves that prevent blood from flowing backwards.
Veins have valves which stop the blood from flowing backwards
Valves.
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.
Valves are needed to prevent blood flowing backwards into the heart.
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
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 - thin membranes found mostly in veins to prevent blood (flowing at relatively low pressures) from flowing backwards.
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.
Valves
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.
