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

the 1st heart sound (lubb)
