Cardiac valves (Figure 2-3).
(a) Between the atrium and ventricle of each side is the
atrioventricular (A-V) valve. Each A-V valve prevents the blood from going back into the
atrium from the ventricle of the same side. The right A-V valve is known as the tricuspid
valve. The left A-V valve is known as the mitral valve. ("Might is never right."). The
mitral valve is sometimes called the bicuspid valve. The leaflets (flaps) of the A-V valves
are prevented from being pushed back into the atria by fibrous cords. These fibrous
