Atrioventricular valves are structures within the heart that prevent the backflow of blood from the ventricles into the atria during contraction. They are located between the heart's upper chambers (atria) and lower chambers (ventricles).
This valve is located between the right atrium and right ventricle, consisting of three flaps that regulate blood flow.
Mitral Valve: Also known as the bicuspid valve, it is situated between the left atrium and left ventricle, featuring two flaps to control blood movement.
This phase refers to the contraction of the ventricles, pushing blood into the pulmonary artery and aorta while atrioventricular valves are closed to prevent backflow
