What valve of the heart has three valves with chordae tendineae?
No, only the atrio ventricular, or the the tricuspid and bicuspid valves, have heart strings
Chordae tendineae are associated with which structure(s)?
Chordae tendineae are associated with the heart, specifically with the atrioventricular valves (tricuspid and mitral valves). They are fibrous cords that attach the valves to the papillary muscles in order to prevent the valves from inverting into the atria during ventricular contraction.
What is the function of the chordae tendineae and the papillary muscles?
The chordae tendinae bring the right ventricular walls closer together, pull semilunar and AV valves open and prevent ballooning of AV valves. The papillary muscles help in the closure and opening of mitral and tricuspid valves.
What is the strings that hold the AV valves open?
Chordae tendineae
The cusps of atrioventricular valves attach directly to?
chordae tendineae
What might be the significance or nonfunctional or defective chordae tendineae?
The chordae tendineae keep the tricuspid and bicuspid valves from compressing past the point of closure when the ventricles contract. If the chordae tendineae were not functioning properly, the pressure from ventricular contraction would force the valve to open into the atrium and cause backward flow of blood. In summary, blood would flow the wrong direction, decreasing the heart's effectiveness.

What structures anchor the atrioventricular valves to the papillary muscles of the ventricle walls?
chordae tendineae
The cusps of atrioventricular valves are attached to papillary muscles by the?
chordae tendineae
What are the cords that hold the two heart valves in place?
Chordae Tendineae
What is connected to the chordae tendineae?
The papillary muscles and cusps of the heart valves.
Is true the chordae tendineae anchor the semilunar valves to the walls of the ventricles?
No. in my opinion, Chordae tendineae is attached to Tricuspid valve and bicuspid valve. Both valves do not have semilunar valves. Pulmonary valve and Aortic valve has semilunar valve.
