Open left ventricle, closed to allow blood to pass from left ventricle to left atrium

Detailed explanation-1: -When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This lets blood flow from the left atrium into the left ventricle. The left atrium contracts. This lets even more blood to flow into the left ventricle.
Detailed explanation-2: -Your mitral valve opens to send blood from your left atrium to your left ventricle. When your left ventricle is full it squeezes, which closes your mitral valve and opens your aortic valve. Your heart sends blood through your aortic valve to your aorta, where it flows to the rest of your body.
Detailed explanation-3: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
