Indicate the Proper Order of Events During the Cardiac

Sequencing
Indicate the proper order of events during the cardiac cycle by placing numbers in the blanks preceding the events in sequence. (Some steps may have been omitted.) The first event is labeled as your starting point.
$\begin{array}{|l|l|}\hline 1& \text {AV valve open; aotic valve closec; ventricular filling occurring } \\\hline &\text { Blood ejected from the ventricles } \\\hline &\text {Is ovolumetric ventricular relaxation } \\\hline &\text {Atrial contraction } \\\hline &\text {AV valve opens; ventricular filling occurs again; one carcliac cycle is complete } \\\hline &\text {Aortic valve opens } \\\hline &\text {SA node discharges } \\\hline &\text {Ventricular filling complete } \\\hline &\text {Ventricular relaxation begins } \\\hline &\text {A artic valve closes } \\\hline &\text {Is ovolumetric ventricular contraction } \\\hline &\text { Ventricular contraction begins; AV valve closes} \\\hline \end{array}$
