Blood cells are a part of blood. Blood is not a part of blood cells. Blood can't flow backward and forward within blood cells. Blood cells can flow backward and forward within blood.

What do the leaflets of the valves do?
They are the shape that they are to fit the vessel that they are between. This permits a tight fit so that when the heart beats, blood flow doesn't go backwards but only forwards.
Does blood flow backwards in elderly people?
Blood veins have valves that prevent blood from flowing backwards.
What disorder causes blood to flow backwards?
mitrovalve prolapse
Why the blood flow backward to the vanes?
blood doesn't 'flow backwards - there are valves in the veins and arteries to stop that happening. Oxygenated blood is sent from the lungs, via the heart - to all parts of the body. When the oxygen has been used up by the cells, the blood returns to the hart through the veins.
If the mitral valve prolapses where does the blood flow to?
If the mitral valve prolapses, the blood may flow backwards into the left atrium.
What do blood vessels have to prevent blood flowing backwards?
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.
Do damaged heart valves allow blood to flow backwards?
The can. A condition called mitral valve prolapse (MVP) is where the mitral, or bicuspid, valve inverts into the left atrium when the left ventricle is contracting causing some of the blood to flow backward from where it came.
What structure prevents blood from backing up?
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.
What happens when blood in capillaries flow the past cells?
Materials needed by the cells move from the blood into the cells, and waste materials move from the cells into the blood.
What cells stop the flow of blood?
platelets
What prevents blood from circulating backward in veins?
Veins contain valves preventing blood from circulating backwards.
What do heart valves do in general?
A heart valve stops the flow of blood backwards when the heart muscle pulses. Without the valve there would be no direction to the flow of the blood.
