Question 14 (1 point) The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. How is this achieved? O Papillary muscles contract and pull the cusps closer to the ventricular wall to prevent cusps inverting into the atria.

2.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

Figure 1: Subvalvular apparatus of the mitral valve (Chordae tendinae and papillary muscles).* The chordae tendinae are the chord like structures connecting leaflets to the papillary muscle. The chordae tendinae are primarily responsible for the end-systolic position of the anterior and posterior leaflets.

3.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

Two papillary muscles, multiple chordae tendineae, an annulus, an anterior and posterior leaflet, and portions of the left ventricular wall make up the mitral valve. In addition to preventing regurgitation, the integration of the mitral valve apparatus into the left ventricle helps to maintain ventricular shape and to coordinate contraction.

4.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

The mean left ventricular ejection fraction following mitral valve replacement with preserved papillary muscles was 0.62 +/- 0.01 and with divided papillary muscles was 0.45 +/- 0.05 (P less than 0.05). The authors conclude that it is important to preserve chordae tendinae and papillary muscles when carrying out mitral valve replacement. PMID:

5.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

The AV valves prevent regurgitation by covering the openings to the atria and forcing blood to exit the heart. To prevent the valves from blowing out under the extremely high blood pressure within the ventricles, the chordae tendineae hold the cusps of each AV valve on the ventricular side.

6.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

Chordae tendineae are attached to _____ muscles that contract just before ventricular walls to _____pressure. chordae tendineae prevent the valves from inverting into the atria during ventricular contraction.

7.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

What are the papillary muscles? The heart’s ventricles, the two bottom chambers, contain muscles known as papillary muscles. These muscles attach to the leaflets of the tricuspid valve and bicuspid (mitral) valve via string-like tendons called the chordae tendineae.. The contraction of these papillaries during systole (rhythmic contraction of the ventricles) facilitates blood flow and …

8.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

papillary muscles. their contraction pulls on and tightens the chordae tendineae, preventing the valv cusps from everting. myocardium. cardiac muscle tissue. … chordae tendineae. tendonlike cords connected to the atrioventricular valve cusps which prevent valve eversion along with papillary muscles. fibrous pericardium.

9.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

Chordae tendineae connect the cusps to papillary muscles. The chordae tendineae prevent the cusps of the AV valves from being shoved up into the atria when the ventricles contract. If this were to happen, blood would regurgitate back into the atria.

10.The coordinated action of chordae tendineae, papillary muscles, and ventricular walls prevent the cusps of the mitral valve from inverting into the atria. how is this achieved?

c. The papillary muscles contract when the ventricle contracts & pull on the chordae tendineae, this keeps the atrioventricular valves from swinging back into the atrium d. Open when blood pressure is greater in the atria e. Close when blood pressure is greater in the ventricle f. Two valves i. Tricuspid valve- between right atrium and …
