The atrioventricular valves of the heart are important in preventing backflow. The mitral valve prevents backflow into the left atrium, and the tricuspid valve prevents backfl â¦ ow into the right atrium.
The valve between the left atrium and left ventricle is called the bicuspid valve. It also allows the flow of blood in one direction. After the oxygenated blood flows from the atrium to the ventricle the valve closes to prevent the blood from flowing back.
