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.
Atrioventricular Valves Function. Av Valves Function. There are four valves, pulmonary, mitrial,tricuspid and aortic in the heart. There is an AV(atrioventricular) node within the heart. When the heart is in diastole, at rest 1/10th second, an electrical impulse begins to emanate from the sinoatrial node. Atrial systole is bought about by the impulse for the sinoatrial node spreading over the artia.
