They are held closed by the chordae tendineae to prevent blood from flowing back into the right atrium.

How do the highlighted valve cusps function during a ventricular contraction? They are pulled open by the chordae tendineae to allow blood to flow into the right ventricle. They are held closed by the chordae tendineae to prevent blood from flowing back into the right atrium. They are pushed open by the increasing blood pressure to allow blood to leave the right ventricle. They are pushed closed by the papillary muscles to prevent blood from flowing back into the right atrium.
