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.
Valves in the heart help to keep the blood flowing in the right direction.
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
It is important for blood to flow in one direction in the heart because blood can't flow backwards because it has oxygen rich blood and poor oxygen rich blood and these to types of blood cannot mix :)
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
the hearts process is to keep the blood flowing through out your whole body
Valves
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.
Your heart is responsible for keeping your blood flowing. It acts like a pump. The right side receives blood from the body where it is pumped to the lungs and the left side pumps the oxygenated blood out to your entire body. The valves of your heart keep it flowing in one direction.

Various valves keep the blood flowing in one direction.
Your heart keeps your blood "flowing"
Other way around. Valves appear in veins to keep the blood flowing in one direction to the heart.

to keep blood flowing in one direction hope this helped you
Valves
The arteries (and arterioles) still carry the pulsing from the heart. By the time the blood flow reaches the capillaries and the veins, it is lost. This helps to keep the blood flowing in the right direction.
