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.
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.

The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
valves help prevent blood from flowing in the wrong direction by opening and closing at the right time to let the heart pump blood effectively.
The heart acts as a pump. When the heart beats, it pumps the blood in one direction.
Valves.
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.
valves
Valves in the heart help to keep the blood flowing in the right direction.
These are valves, and are found in veins to prevent blood from flowing backwards.
Valves prevent the backflow of blood, in this case the semilunar valves stop blood flowing back into the heart.
