but valve closure is a passive event caused by an attempt at retrograde blood flow.

What valves open when the atria contract?
tricuspid valve
Which valves in the heart are open during diastole?
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.
Are the tricuspid valves of the heart also called semilunar valves?
The tricuspid valves are different from the semilunar valves. The tricuspid valve is the right atrioventricular valve.
What is the name of the valve that opens to allow blood to travel from the atrium to the right ventricle?
tricuspid/ right atrioventricular valve.
What is Tricuspid valve stenosis?
usually doesn't require treatment. However, if there is damage to other valves in the heart as well, then surgical repair or replacement must be considered.
Bicuspid and tricuspid valves open in what direction?
The bicuspid (mitral) valve and tricuspid valve open in a direction that allows blood to flow from the atria to the ventricles.
What valves open when the atria contract?
tricuspid 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 at the bottom of the right atrium prevents the backward flow of blood.
What is blood flow from tricuspid valve from feet?
The Tricuspid valve is in the heart, not the feet
The right atrioventricular valve is known as the?
Another name for the right atrioventricular valve is the tricuspid valve. (3 -tri- on the right; 2 on the left/mitral valve)
Which is more complex tricuspid or mitral valve?
Tricuspid valve is more complex as compared to bicuspid valve .
Compare the structure of the tricuspid valve with that of the pulmonary valve?
the tricuspid valve is alot larger than the pulomonary valve beyaaaaaaaaah
Tricuspid valve were is it located?
The tricuspid valve is located between the right atria and ventricle.
Which valves in the heart are open during diastole?
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.
True or False the tricuspid valve is closed while the atrium is contracting?
False. The valve is open so that the blood can be pumped to the ventricles.
What happens when the ventricular walls contracts?
The bicuspid valve opens and the tricuspid valve closes.
The mitral valve has chordae but the tricuspid valve does not?
no
