These are valves, and are found in veins to prevent blood from flowing backwards.
The flaps are called valves - they are present in large veins to make sure blood does not flow in the opposite direction and keeps flowing toward the heart.

We calls the flaps valves. There are also some in the veins that bring blood back to the heart.

EMF (voltage) is the force that keeps current flowing in a circuit.
The cardiovascular system. It provides nutrients and oxygen to the entire body and removes waste and carbon dioxide through the circulation of blood. The pumping action of the heart keeps the blood flowing through the vessels and the system pressurized.
What keeps our reservoirs full and rivers flowing
In electronics, a diode is a component that restricts the directional flow of charge carriers. Essentially, a diode allows an electric current to flow in one direction, but blocks it in the opposite direction. Thus, the diode can be thought of as an electronic version of a check valve. Circuits that require current flow in only one direction typically include one or more diodes in the circuit design.
The bone tissue gets you to stop bleeding if you got heart the heart tissue keeps your heart from getting hurt
The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
The heart acts as a pump. When the heart beats, it pumps the blood in one direction.
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.
They ensure that the blood flows only in one direction (back toward the heart).

Your heart keeps your blood "flowing"
There are valves in the heart which open and close that allow the blood to be pumped in one direction only. See the related link for more information.

The heart has valves for to allow blood flow in one direction only. They close as the blood passes each. Hooweestik.
