how many heart strings do we have

The human heart has about 60 to 90 heartstrings , medically known as the chordae tendineae. These are tough, tendinous cords that connect the papillary muscles inside the ventricles to the atrioventricular valves (tricuspid valve on the right and mitral valve on the left). Their function is to prevent the valves from inverting or prolapsing during ventricular contraction, thus ensuring one-way blood flow through the heart. Most sources agree on roughly 80 chordae tendineae in total, but the exact number can vary between individuals.
