Chordae tendineae (or simply chordae) are fibrous cords or tendons that are present in the heart to anchor the atrioventricular (AV) valves (specifically, the tricuspid and bicuspid/mitral valves) to the papillary muscles located in the ventricles. This prevents the valves from inverting into the atria when the ventricles contract and helps in maintaining proper valve function. Therefore, the correct location for chordae tendineae is Ventricles
