The mitral valve is located between the left atrium (LA) and left ventricle (LV). When oxygenated blood comes from the lungs into the LA, it goes from the LA to the LV (diastole). When the LV contracts (systole), it pumps the blood from the LV to the aorta for circulation throughout the body. The mitral valve prevents blood from going up to the LA when the LV contracts, because all the blood should go to the aorta, not back up to where it came from (LA). The mitral valve shuts when the LV contracts, and reopens when the LV relaxes, to allow for filling of the LV again. In short... the mitral valve prevents blood from going up from the LV to the LA during ventricular contraction.
