Explanation:
Detailed explanation-1: -Mitral valve: This valve has two leaflets. They allow blood to flow from the lungs into the left atrium. And they prevent backward flow from the left ventricle to the left atrium.
Detailed explanation-2: -After the left ventricle contracts, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle.
Detailed explanation-3: -When the ventricles contract, the blood should go out of the heart and not back to the atrium. This backflow of blood is prevented by valves. Tricuspid valve prevents backflow of blood from right ventricle to right atrium. Bicuspid valve prevents backflow of blood from left ventricle to left atrium.
