Mitral regurgitation is a leakage of blood that flows backward via the mitral valve during contraction of the left ventricle which results in systolic murmur.
<u>Explanation:</u>
Mitral valve is seen between the left atrium and left ventricle,it prevents the back flow of blood during left ventricular contraction.
