When the ventricles relax, atrial pressure exceeds ventricular pressure, the AV valves are pushed open and blood flows into the ventricles. However, when the ventricles contract, ventricular pressure exceeds atrial pressure causing the AV valves to snap shut. To ensure that the AV valves do not evert (turn inside-out), they are attached to small papillary muscles by tough tendons called the cordae tendineae.
