Bicuspid Valve (Mitral Valve)
Entrance valve that sees only oxygenated blood
Tricuspid
Entrance valve that sees only unoxygenated blood
Aortic Valve
Exit valve that sees only oxygenated blood
Pulmonic Valve
Exit valve that sees only unoxygenated blood
Gallop Rhythm
Extra heart sounds (S3, S4) that sound like a racing horse
S1
Heart sound created by the closure of the AV valves at the beginning of ventricular contraction
S2
Heart sound created by the closure of the semilunar valves at the beginning of ventricular relaxation
Incompetent Valve
Leaky valve that allows backflow of blood
Stenosis
Refers to the narrowing of a valve
Aortic Valve
Semilunar valve through which blood leaves the left ventricle
Pulmonic Valve
Semilunar valve through which blood leaves the right ventricle
Chordae Tendineae
Tough bands that attach the AV valves to the ventricle walls
Mitral Valve (Bicuspid Valve)
Valve that prevents the backflow of blood "from" the Left Ventricle
Aortic Valve
Valve that prevents the backflow of blood "into" the Left Ventricle
Pulmonic Valve
Valve that prevents the backflow of blood from the pulmonary artery
Bicuspid Valve
called the "mitral valve"
S1
