The charade tendineae are necessary for the proper functioning of the
A
SA node
B
Pericardium
C
Pulmonic semilunar valve
D
Mitral valve
Explanation: 

Detailed explanation-1: -Due to the blood turbulence AV valve closes.-Thus function of chordae tendineae is to anchor the AV valves to ventricular papillary muscles and keep the AV valves in a closed position during ventricular systole to prevent the backflow of blood into the atria.

Detailed explanation-2: -Mitral valve (MV) closure depends upon the proper function of each component of the valve apparatus, which includes the annulus, leaflets, and chordae tendineae (CT).

Detailed explanation-3: -The chordae tendinae are primarily responsible for the end-systolic position of the anterior and posterior leaflets. Arising from the papillary muscles, they are classified according to their site of insertion between the free margin and the base of leaflets (Figure 1).

Detailed explanation-4: -The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles. These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.
