<p>1- atrial contraction. 2- ventricular isovolumetric contraction (both valves r closed).(av closed) 3- rapid ventricular ejection (semi-lunar valves r open, av closed) 4- slow ventricular ejection (semi-lunar closed, atria filling. 5- ventricular isovolumetric relaxation , both valves r closed. (semi-lunar closed). 6- ventricular filling (mitral opens). 7- diastole.</p> Signup and view all the answers
