THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Additional Information: If chordae tendineae does not work properly then valves will not function properly. This causes backflow of the blood in atria. Such a condition is called Heart regurgitation in Mitral Regurgitation in which the mitral valve does not close properly.

Detailed explanation-2: -The mitral valve (MV) is a very complex structure composed of the anterior (AML) and posterior (PML) leaflets, the chordae tendineae (CT), and the papillary muscles (PPMM), all of which work on a very harmonious basis to ensure an appropriate opening and closing of the left atrioventricular orifice.

Detailed explanation-3: -Chordae tendineae maintain the position and tension of the atrioventricular valves (tricuspid and bicuspid valves). They maintain the one-way blood flow from the auricle to the ventricles.

Detailed explanation-4: -The chordae provide the critical function of anchoring the mitral leaflets during systole, allowing for symmetric coaptation and preventing prolapse of the leaflets into the LA. The chordae are attached to the LV via the papillary muscles.
