The Aorta
A. systole causes a complete emptying of all blood from the ventricle B. systole increases the pressure in the ventricles ejecting blood out through the cardiac outflow tracts C. systole occupies a longer period of time than does diastole. D. systole is the phase of the cardiac cycle when the heart fills with blood. E. None of the above
ventricular systole
Pressure in aorta is greatest during ventricular systole.
Systolic Blood Pressure.
ventricular systole
Systolic Pressure
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)

yes during ventricular systole AV valves are closed.
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
