Prevents backflow into the left atrium
A
Mitral/Bicuspid valve
B
Tricuspid valve
C
Right atrium
D
None of the above
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: -Mitral valve: Allows blood to flow into the left ventricle; prevents blood from flowing back into the left atrium.

Detailed explanation-3: -The bicuspid valve prevents backflow from the left ventricle into the left atrium. The semilunar valves prevent backflow into the ventricles from the aorta and pulmonary arteries.

Detailed explanation-4: -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.

Detailed explanation-5: -The aortic valve prevents backflow from the aorta into the left ventricle, and the pulmonary valve prevents backflow from the pulmonary artery into the right ventricle.
