Vedclass · Answer

(D) The heart produces two main sounds during each cardiac cycle,known as 'lub' and 'dub'.$1$. The first heart sound,'lub',is produced during the closure of the atrioventricular valves (the bicuspid and tricuspid valves) at the beginning of ventricular systole.$2$. The second heart sound,'dub',is produced during the closure of the semilunar valves at the beginning of ventricular diastole.Therefore,the 'lub' sound is associated with the closure of both the bicuspid and tricuspid valves.

The 'lub' heart sound is produced during the closure of which valves?
