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.
What structures anchor the atrioventricular valves to the papillary muscles of the ventricle walls?
chordae tendineae
What are threads that attach the valve flaps to the ventricle walls called?
chordae tendineae
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
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 are the functions of the chordae tendineae and papillary muscle?
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.
What is secreted by cells in the walls of the hearts atria?
atrial natriuretic hormone (ANH)
What are the little cords of connective tissue that attach the free edges of an artrioventricular valve to t he walls of a ventricle?
chordae tendinae
What percent of blood pass from the atria to the ventricles before the atrial walls contract?
70% the remaining 30% is pushed into the ventricles during atrial systole
What is the rough wall of the atrial wall called?
The atrial walls inside the heart are made of endothelium and are called endocardium. They are made of the same tissue as the insides of veins and arteries.
What is the medical term meaning rupture of a vessel?
Cardiorrhexis is rupture of the heart (cardio=HEART; rrhexis=RUPTURE). Myocardial rupture (or heart rupture) is a laceration or tearing of the walls of the ventricles or atria of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae or of one of the valves of the heart. It is most commonly seen as a serious sequela of an acute myocardial infarction (heart attack).Myocardial rupture (or heart rupture) is a laceration or tearing of the walls of the ventricles or atria of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae or of one of the valves of the heart.

Why are ventricle walls pitted?
Pitted to allow expandibility. Folds of the "pits" are where papillary muscles arise that are used as attachment points for the chordae tendinae that control the A-V valves.
