Answer:
b. isovolumetric contraction, ventricular ejection, isovolumetric relaxation
Step-by-step explanation:
Cardiac cycle is performed by our heart . Cardiac cycle starts from the ending of one heartbeat to the beginning of next heart beat. There is a complete relaxation of both atria and ventricles. Approximately, cardiac cycle lasts 0.8 seconds. The correct order of cardiac cycle is- iso-volumetric contraction, ventricular ejection, iso-volumetric relaxation.
