Tricuspid valve
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, between the right atrium and the right ventricle. The function of the valve is to prevent back flow of blood into the right atrium.
==Structure==
The normal tricuspid valve usually has three leaflets and three papillary muscles. They are connected to the papillary muscles by the chordae tendineae, which lie in the right ventricle. Tricuspid valves will not always consist of three leaflets and may also occur with two or four leaflets; the number may change during one's lifetime.〔Richard Van Pragh: Cardiac anatomy in A. C.
