What is the role of the tricuspid valve?

The tricuspid valve is located on the right side of the heart between the right atrium and ventricle. The purpose of the valve is to close when the ventricle pumps blood into the pulmorary arteries that lead to the lungs. The bicuspid valve, or mitral valve, functions similarly to maintain blood flow in one direction only. The bicuspid valve is located on the right side of the heart. Oxygenated blood from the left ventricle is pumped throughout the body as the mitral valve stays closed during compression.
