Atrioventricular valves are two in number. Mitral valve is between the left atrium (upper chamber) and left ventricle (lower chamber). Tricuspid valve is between the right atrium (upper chamebr) and right ventricle (lower chamber). Mitral valve closes when the left ventricle contracts, to prevent back flow of blood into the left atrium. Tricuspid valve closes when the right ventricle contracts. Hence the blood from the ventricles are able to go out of the heart into the blood vessels during ventricular contraction. Mitral and tricuspid valves open when the ventricles relax, permitting blood to enter the ventricles from the atria. This blood is pumped out when the ventricles contracts next time.

How does the aortic semilunar valve differ from the bicuspic valve in appearance?
Semilunar valves include the aortic and pulmonary valves of the Heart. These valves do not have chordae tendineae, and are more similar to the valves in veins. Tricuspid vales are composed to three cusps which are attached with papillary muscles with the help of chordae tendineae.
