The mitral valve prevents blood from flowing back from the left ventricle to the left atrium in the heart.
Pulmonary arteries.
Blood in this case is low in oxygen.
pulmonary arterie
Blood flows from the heart into the left atrium, into the left ventricle. From there, it flows from the right artrium into the left ventricle.
The bicuspid valve is the valve that separates the left ventricle from the aorta.
The valve that stops blood from flowing back into the right atrium is the tricuspid valve. It is located between the right atrium and right ventricle and ensures that blood flows in one direction, from the atrium to the ventricle.
the aortic valve
The aortic valve. When the left ventricle contracts, blood is ejected into the aorta. When the left ventricle relaxes the aortic valve stops blood from flowing from the aorta back into the left ventricle.
blood vessels
a blood vessels transport blood to all parts of the body
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
