WebAll steps. Final answer. Step 1/2. 1. During ventricular systole, the ventricles of the heart contract to pump blood into the aorta and pulmonary artery. This phase is divided into two stages one is isovolumetric contraction and the other is ventricular ejection. View the full answer. Step 2/2. Final answer. WebS3 occurs in early diastole, when the ventricle is dilated and noncompliant. It occurs during passive diastolic ventricular filling and usually indicates serious ventricular dysfunction in adults; in children, it can be normal, sometimes persisting even to age 40. S3 also may be normal during pregnancy.

WebDiastole - Diastasis (dī-as'tă-sis): During the second 1/3 of diastole there is very little change in ventricular volume. As the ventricles near capacity passive inflow of blood slows.
