Systole occurs when the heart contract himself to expulse blood to the vessels, and when the heart relaxes while it fulfills of blood is called diastole.  During the systole process the tricuspid valve needs to be closed to allow the increase of pressures inside the heart cameras and then allow the expulse of blood.
