Isovolumetric contraction is when the ventricles contract without ejecting blood because the pressure is high enough to close the AV valves but not open the semilunar valves.
1. Contraction w/o ejection of blood 2. Pressure in ventricles is high enough to <b>close AV</b> valve but not high enough to open semilunar valve <img src="paste-7d85a111618eb1d25f2287d413688235961b374c.jpg">
