Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
Valves open and close and make sure that the blood doesnt go backwards
Yes, in some states of pulmonary Hypertension.
The valves, in either atrium.
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.
Valves control the flow of blood. Without them blood could flow backwards.--------------------------Yes, true. Valve would maintain one way traffic for blood right from the heart and to outside parts of the body and form outside to the heart.
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.

Valves are needed to prevent blood flowing backwards into the heart.
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.
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.
Because the heart is designed to pump forward and the vascular system has valves that stop blood from moving backwards.
The heart valves ensure that once blood has passed through them, into or out of the heart, it can not flow backwards.

Atrioventricular valves prevent backwards flow of blood inside the heart, i.e. flow from the ventricles back to the atria. Semilunar valves prevent backwards flow of blood into the heart from the aorta (left ventricle) or the pulmonary arteries (right ventricle).
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
yes they are, only separated by small valves,which are there to prevent the backwards flow of blood

Blood is a constant whereabout in our bodies. As of such a frequent heartbeat exists within our system. Which causes the blood within our bodies to flow forward, in lamense terms it produces a very large push for the blood to distribute it's nutrients throughout the body and back within our heart and out again. This constant push is what prevents blood from flowing backwards in your veins.
