The chordae tendinae connect the bicuspid and tricuspid valves to the papillary muscles. the tendinae keep the valves shut during systole. During diastole, when the chambers fill with blood, the papillary muscles contract, pulling the tendinae, thus opening the valves.
papillary muscles
Chordae tendinae is attached to papillary muscle and the valves.
papillary muscles
The chordae tendineae connect the AV valve and the papillary muscle. These structures work together to prevent backflow from the ventricle to the atrium.
papillary muscles
cardiac muscle. a type of cardiac muscle is the papillary muscles attach to the lower portion of the interior wall of the ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles opens these valves. When the papillary muscles relax, the valves close.
Papillary muscles in the heart are responsible for anchoring the chordae tendineae, which are fibrous cords that attach to the heart valves (mitral and tricuspid). Their main role is to prevent the valves from prolapsing into the atria during ventricular contraction and to ensure proper valve closure, which helps maintain efficient blood flow through the heart.
The chordae tendinae and their attachments to the papillary muscles prevent the AV valves from collapsing backwards into the atria.
Semilunar valves include the aortic and pulmonary valves of the Heart. These valves do not have chordae tendineae, and are more similar to the valves in veins. Tricuspid vales are composed to three cusps which are attached with papillary muscles with the help of chordae tendineae.

The heart strings, or chordae tendineae, are made of collagenous fibers similar to those found in tendons because both structures provide strength and flexibility. This collagen composition allows the chordae tendineae to effectively anchor the heart valves to the heart muscle, ensuring they open and close properly during the cardiac cycle. The tensile strength of this material prevents the valves from prolapsing, maintaining efficient blood flow. Thus, the similarity in composition supports both structural integrity and functional performance in the heart.
