Considering the left ventricle, why does the ventricular volume have to decrease during ventricular systole? The AV valve needs time to shut before the ventricle can eject blood O Ventricular pressure is greater than atrial pressure so the ventricle cannot eject blood Aortic pressure is higher than ventricular pressure and the ventricle must pressurize the blood to open the aortic outflow valve O The ventricle is still filling with blood and therefore cannot eject blood during this time O The ventricle needs to pressurize the blood to close the aortic outflow valve « Previous
