I found a similar question. If the attached document is the same as your supposed question, then my answer are below.
AV valves open - atrial pressure is greater than ventricular pressure
AV valves closed - Ventricular pressure rises above atrial pressure
Semilunar valves closed - ventricular pressure is lower than arterial pressure
Semilunar valves open - pressure in the ventricles is greater than the pressure in the great arteries
Reproduction cells, I think...
Hope this helps xox :)
