Mitral valve

Mitral valve: Valve with two leaflets, between the left atrium (upper chamber) and left ventricle (lower chamber). It is called so because it resembles the head wear of the bishop (mitre). Mitral valve prevents leakage of blood from the left ventricle to left atrium when it contracts. The mitral valve leaflets are held taut during contraction of left ventricle by structures known as ‘chordae tendinae’ which are in turn connected to ‘papillary muscles’ arising from the walls of the left ventricle.
