What is the function of the tricuspid valve?

Prevent backflow into the right atrium

The function of the tricuspid valve is to prevent backflow into the right atrium. This valve is located between the right atrium and the right ventricle of the heart. When the right ventricle contracts to pump blood into the pulmonary artery (which carries blood to the lungs for oxygenation), the tricuspid valve closes to ensure that blood does not flow backward into the right atrium. This one-way flow is crucial for maintaining proper circulation within the heart and ensures that oxygen-poor blood is efficiently directed towards the lungs. The proper functioning of the tricuspid valve is essential to prevent any disruption in the heart's pumping cycle and to maintain effective blood circulation throughout the body.
