What is "tricuspid valve"?

The tricuspid valve is one of the four valves in the human heart, specifically located between the right atrium and right ventricle. It is named after its three leaflets, or cusps, which open and close to control the blood flow. When the right atrium contracts, the tricuspid valve opens, allowing blood to flow into the right ventricle. When the ventricle contracts, the valve closes to prevent the backflow of blood into the atrium. This helps maintain the proper direction of blood flow and ensures efficient pumping of oxygen-depleted blood to the lungs for oxygenation.
