What are the tricuspid valves?

The tricuspid valve is on the right side of the heart. It separates the upper and lower chambers, also known as the right atrium and ventricle. The valve allows deoxygenated blood to flow through both of the chambers. The right ventricle pumps blood to the lungs, where it will be oxygenated.

What is tricuspid annulus?

The tricuspid annulus forms the boundary between the tricuspid valve leaflets and their surrounding perivalvular tissue of the right atrioventricular junction. Its shape changes throughout the cardiac cycle in response to the forces from the contracting right heart myocardium and the blood-valve interaction.

How do the tricuspid and bicuspid valves work?

When the right ventricle is full, the tricuspid valve closes and keeps blood from flowing backward into the right atrium when the ventricle contracts (squeezes). When the left ventricle is full, the mitral valve closes and keeps blood from flowing backward into the left atrium when the ventricle contracts.
