Vedclass · Answer

(C) The cardiac cycle involves a sequence of events where the atria contract first,followed by the ventricles. The atrial systole lasts for approximately $0.1\,	ext{seconds}$. The electrical impulse generated by the $SA$ node causes atrial contraction,and there is a slight delay (about $0.1\,	ext{seconds}$) at the $AV$ node before the impulse reaches the ventricles to initiate ventricular contraction. Therefore,ventricular contraction is preceded by atrial contraction by approximately $0.1\,	ext{seconds}$.
