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.
marginal
Identify the highlighted artery. circumflex marginal right coronary left coronary
right auricle
Identify the highlighted structure. left atrium right auricle right atrium left auricle
tricuspid valve
Identify the highlighted structure. tricuspid valve pulmonary semilunar valve mitral valve aortic semilunar
