The bicupid and tricuspid valves close during ventricular contraction. This prevents the backflow of blood from the ventricles to the atria.
left ventricle
Due to pressure changes in different chambers of the heart. For example, when the atria contract, the bicuspid and tricuspid valves open. They get closed, when the ventricles contract. When the ventricles contract the aortic and pulmonary valves open. Aortic and pulmonary valves close, when the ventricles relax.
The bicuspid (mitral) valve and tricuspid valve open in a direction that allows blood to flow from the atria to the ventricles.
By minute electrical singles produced by the heart itself to open and close the valves.
The bicuspid and tricuspid valves are located between the atria and the ventricles. The bicuspid or mitral valve is on the left, and the tricuspid is on the right.
Bicuspid means having two valves. A normal heart contains tricuspid valves.
the mitral valve is the given name for it, while the bicuspid valve is the technical name for it.
During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
When the atria contract, there is increase in pressure in the atrial chambers. So both bicuspid and tricuspid valves opened up. When both the ventricles contract, both the bicuspid and tricuspid valves get closed. This opens up the aortic and pulmonary valves.

The tricuspid and bicuspid valves block blood from coming back into the atria.
