Close heart valves: The chordae tendineae are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart. These muscles and tendons allow these valves to remain closed against the pressures generated by the contraction of the ventricles.

Hold valve: Think of valve as a parachute, chordae tendinae are the "ropes" that anchor the valve leaflets or cusps to the heart muscle. Heart muscle contraction pulls on these cords to close the valve, when when heart relaxes then the valve opens. They are an important part of the heart valve apparatus.
