Vedclass · Answer

(D) Diastole refers to the relaxation phase of the heart chambers. During ventricular diastole,the ventricles relax,which allows the pressure inside them to decrease. This drop in pressure causes blood to flow from the atria into the ventricles. Simultaneously,during atrial diastole,blood from the vena cava and pulmonary veins enters the atria. Therefore,the primary event during diastole is the filling of the heart chambers with blood.
