Blood vessels cant flow backwards because there is other blood forcing it to move forward. This is propelled by the heart, which is like a pump, and pushes blood around the body until it reaches the heart again. The only way blood could flow backwards was if the heart stopped.

Why doesnt blood ever flow the wrong way?

Valves inside the veins prevent blood from flowing where?

What kind of flaps in the heartstop blood from flowing the wrong way?
Valves - thin membranes found mostly in veins to prevent blood (flowing at relatively low pressures) from flowing backwards.
What structure prevents blood from backing up?

How does the blood to a heart and lung keep flowing in the same direction?
There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
What prevents blood from flowing in veins?
