Prevents backflow: It prevents blood from going backwards from the left ventricle to the left atrium with each beat of the heart.

Mitral valve: The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common.

One of 4 heart valve: The mitral valve is one of the 4 heart valves found in the heart. These valves keep blood moving one direction rather than back and forth as the heart contracts. The mitral valve is so named as it looks like the pope's hat (a mitre). The mitral valve separates the left atrium and the left ventricle.
