The tricuspid valve is located in the heart and is known as the 'tricuspid valve' because it is formed from three (tri-) cusps.
The tricuspid valve consists of three flaps known as 'cusps' attached to the walls between the right atrium (RA) and the right ventricle (RV). This valve enables blood to pass from the right atrium of the heart to the right ventricle of the heart - while also preventing flow of blood in the opposite direction.
The cusps of the tricuspid valve work in the same way as the cusps of the bicuspid valve. That is, in order for blood to pass from an atrium to a ventricle, an atrioventricular valve must open. The opening and closing of these valves is controlled by the difference in pressure across the atrioventricular valves.
