Your heart is constantly is constricting and expanding which is what makes your blood flow. One part of the heart pumps in blood while the other part pumps out blood making a thud dud kind of noise.
The heart valves.
The first sound of a heartbeat is caused by the closing of the atrioventricular valves (mitral and tricuspid valves) in the heart and marks the beginning of ventricular systole, where the ventricles contract to pump blood. This sound is known as the "lub" sound of the heartbeat.

Heartbeat. By Taana Gardner
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.
I don't think so but I do know that Chevrolet is the heartbeat of America.
