Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mitral valve prolapse causes blood to leak back into the ____ when the ventricles contract.
A
pulmonary arteries
B
left atrium
C
right atrium
D
aorta
E
pulmonary trunk
Explanation: 

Detailed explanation-1: -A prolapsed mitral valve means that the valve’s flaps do not always fit and close properly between each beat of the heart, which may cause the valve to leak blood backward through the valve back to the left atrium. This condition is called mitral valve regurgitation.

Detailed explanation-2: -In mitral valve prolapse, the leaflets of the mitral valve bulge (prolapse) into the left atrium like a parachute during the heart’s contraction. Sometimes mitral valve prolapse causes blood to leak back into the atrium from the ventricle, which is called mitral valve regurgitation.

Detailed explanation-3: -In mitral valve prolapse, the valve flaps bulge into the upper left chamber during each heartbeat. Mitral valve prolapse can cause blood to leak backward, a condition called mitral valve regurgitation.

Detailed explanation-4: -In aortic valve regurgitation, the valve doesn’t close properly, causing blood to leak back into the heart’s main pumping chamber (left ventricle).
