The "lub-dub" sound of the heartbeat is produced by the closing of the heart valves. The "lub" (first heart sound) occurs when the atrioventricular valves close as the ventricles contract, while the "dub" (second heart sound) happens when the semilunar valves close as the ventricles relax. This cyclical opening and closing of the valves during the cardiac cycle generates the characteristic sounds associated with a heartbeat.
