The tricuspid valve, also called the right atrioventricular valve, gets its name because it is generally considered to have three leaflets: the anterior, posterior and septal leaflets. Of these, the anterior, also called the infundibular or anterosuperior, leaflet is typically the largest.
The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or âregurgitatingâ back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves. 1  Atrioventricular valves. The atrioventricular (AV) valves are located in the middle of the heart between the atria and ventricles and only allow blood to flow from the atria into the ventricles. 2  Semilunar valves.
