(B) The cardiac cycle involves two primary heart sounds,commonly referred to as 'lub' and 'dub'.$1$. The first heart sound,'$S_1$' or 'lub',is produced by the closure of the atrioventricular valves (tricuspid and bicuspid/mitral valves) at the beginning of ventricular systole.$2$. The second heart sound,'$S_2$' or 'dub',is produced by the closure of the semilunar valves (aortic and pulmonary valves) at the end of ventricular systole.Therefore,the first heart sound is associated with the closure of the tricuspid and bicuspid valves.
