Another name for the bicuspid heart valve?
There are two Atrioventricular Valves in the heart. The first one, on the right side of the heart, is called the Tricuspid Valve (it has three 'flaps'). On the left side, the Atrioventricular Valve is called the Bicuspid or Mitral Valve (it has two 'flaps')
Valve with two flaps found on the left side of the heart?
Mitral Valve
Do papillary muscles prevent the AV valves from prolapsing excessively into the atria when the ventricles contract?
Papillary muscles are connected to the chordae tendonae on the AV valves. During ventricular systole ( contraction of the ventricles) the papillary muscles contract preventing regurgitation of blood back into the atriums.
Where does blood flow after the right AV valve?
After the right AV valve, the blood flows into the right ventricle.
How many flaps of tissue make up the valves between the right atrium and right ventricle?
The antrioventricular valve has two valves. The bicuspid valve has 2 flaps and in located in the right ventricle/right atrium. The tricuspid valve has 3 flaps and is located in the left ventricle/left atrium.
What AV valve has two flaps?
the bicuspid valve.
AV valve with 3 flaps?
tricuspid
AV valve with three flaps?
Bicuspid valve.. a birth defect of the aortic valve.
How many flaps does the aortic valve have?
The antrioventricular valve has two valves. The bicuspid valve has 2 flaps and in located in the right ventricle/right atrium. The tricuspid valve has 3 flaps and is located in the left ventricle/left atrium.

The string-like structures that anchor the valve flaps of the AV valves are called?
The string-like structures that anchor the valve flaps of the AV valve are called the chordae tendinae, which attach to the papillary muscles of the ventricles. Interestingly enough, the bundle branches extend down and into the areas where the papillary muscles are located, and the resulting contraction of the ventricles ensures that the papillary muscles pull the valves tight, ensuring that they are closed thoroughly to prevent backflow in the heart.
Do papillary muscles prevent the AV valves from prolapsing excessively into the atria when the ventricles contract?
Papillary muscles are connected to the chordae tendonae on the AV valves. During ventricular systole ( contraction of the ventricles) the papillary muscles contract preventing regurgitation of blood back into the atriums.
What is the function of the bicuspid valve?
The Bicuspid Valve is much like the Tricuspid Valve. It allows blood to flow through into the ventricle, but prevents blood from entering back into the atrium. The difference is it only has two flaps instead of three.
Where does blood flow after the right AV valve?
After the right AV valve, the blood flows into the right ventricle.
What AV and semilunar valve positions during ventricular diastole?
The AV valve is open and the semilunar valve is closed during ventricular diastole.
What event within the heart causes the AV valves to open?
The AV valves open when the blood pressure exerted on their atrial side is greater then on the ventricle side. This happens when blood returning to the heart fills the atria and puts pressure against the valve. Note : When heart is completely relaxed, the AV valve flaps hang limply into the ventricle chamber (open) allowing blood from the atria to flow through them directly to the ventricle. Thus, it is the result of ventricle contraction which closes the AV valves and moves them from their resting state (open).
