What makes the first sound of a heartbeat?

Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
What makes the lub sound of our heartbeat?
The "lub" sound of our heartbeat, known as the first heart sound (S1), is primarily caused by the closure of the atrioventricular (AV) valves—the mitral and tricuspid valves—during ventricular contraction (systole). When the ventricles contract, blood is pumped out of the heart, and the sudden closure of these valves creates a distinct sound. This sound is essential for indicating that the heart is properly pumping blood and is part of the normal cardiac cycle.
