WebDuring ventricular filling, the leaflets of each AV valve begin to close; with the onset of atrial systole, the partially closed leaflets reopen. When atrial systole ends, the ventricle recoils and the leaflets close. Following closure, the AV valves are stretched toward the atrium by the momentum of the ventricular blood mass.
