Tricuspid valve
One-way valve present between right auricle and right ventricle / From Wikipedia, the free encyclopedia
"Tricuspid" redirects here. For the type of tooth, see dental anatomy.
For the semilunar valves, the other two of the three heart valves that are usually tricuspid, see pulmonary valve and aortic valve.
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle. The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular contraction (systole).
