WebVentricular systole: lasts about 0.3 seconds - both ventricles contract, blood is forced to the lungs via the pulmonary trunk, and the rest of the body via the aorta. Atrial diastole: lasting about 0.7 seconds - relaxation of the atria, during which the atria fill with blood from the large veins (the vena cavae). WebJan 11, 2024 · The normal blood pressure for a healthy adult should measure between 90 mmHg and 119 mmHg for systolic blood pressure and between 60 mmHg and 79 for diastolic blood pressure.
