Why do vein have one-way valve?
The one way valve prevent blood seeping backwards (downwards) due to gravity. For instance, if a valve in the leg fails or doesn't work properly, Varicose veins (swollen and enlarged veins) will occur.

What is the function of valves in veins in the legs?
The valves help to prevent blood from seeping backwards. They provide a one way valve. When valves begin to fail blood may become stagnant and cause unsightly varicose veins - usually in the legs..

What is the structure that keeps blood from flowing backwards?
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.
What keeps the blood from flowing back into a chamber of the heart?
A specific chamber? It's valves and each one has a different name. I'll list the chamber and the valve which stops 'backflow':- Right Atrium: Tricuspid valve Right Ventricle: Pulmonary valve Left Atrium: Mitral valve Left Ventricle: Aortic valve The valves basically open when the relevant chamber is pumped but when pressure goes back towards the chamber they snap shut, stopping blood from going back through the heart/circulatory system.
What prevents blood from flowing back into the heart?
The valve
What if the name of the valve on the vessel that takes blood from the heart?
The valve on the aorta (the vessel taking blood away from the heart) is called the "aortic valve".
What is the name of the valve that opens to allow blood to travel from the right atrium to the right ventrcle?
The tricuspid valve is the valve that opens to allow blood to flow from the right atrium to the right ventricle in the heart. This valve prevents blood from flowing back into the right atrium when the right ventricle contracts.
Where does blood go after the aortic valve?
blood flows through the mitral valve (left atrio-ventricular valve/bicuspid valve) into the left ventricleThe Left VentricleIt then goes through the left ventricle into the aorta, which pumps blood throughout your body.left ventricle.Blood goes to left ventricle. From there your blood goes to the body via aorta.
