The Cardiac Cycle 1. What event occurs when the pressure in the left ventricle rises above that in the left atrium? 2. During ventricular systole, the blood volume in the atria is (increasing/decreasing), and the volume in the ventricles is (increasing/decreasing). 3. What event occurs when the pressure within the left ventricle becomes greater than the pressure within the aorta? 4. During isovolumetric contraction, pressure is highest in the 5. During what part of the cardiac cycle is blood pressure highest in the large systemic arteries?
