tricuspid valve
mitral valve
The mitral valve prevents a backflow of blood into the left atrium. It closes when the heart contracts, preventing blood from flowing back. Other valves like the aortic and tricuspid have different functions.
The mitral valve, also known as the bicuspid valve, is the valve that prevents a backflow of blood into the left atrium. This valve is located between the left atrium and the left ventricle. When the heart contracts, the mitral valve closes, preventing blood from flowing back into the atrium. The other valves listed, the aortic valve and the tricuspid valve, have different functions.
