In the cardiac cycle, blood flowing into the heart is called the systole.

There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
Valves prevent the backflow of blood, in this case the semilunar valves stop blood flowing back into the heart.

Blood is a constant whereabout in our bodies. As of such a frequent heartbeat exists within our system.

This constant push is what prevents blood from flowing backwards in your veins.

All the blood flowing through the intestines passes through the liver on its way back to the heart.
Tiny valves in your veins keep blood from backing up. The pumping force of your heart keeps the blood flowing forward. If a valve in your leg stops working properly, the blood seeping back causes varicose veins mainly in your legs, though can occur anywhere.
