What occurs in the Atria valve?

The atrioventricular (AV) valves, consisting of the mitral and tricuspid valves, are located between the atria and the ventricles of the heart. They open to allow blood to flow from the atria into the ventricles during diastole (the relaxation phase) and close during systole (the contraction phase) to prevent backflow. Proper functioning of these valves is crucial for maintaining efficient blood circulation throughout the heart and body. Any dysfunction can lead to conditions like regurgitation or stenosis, affecting overall heart health.
