Explanation:

The left AV valve is called the mitral valve. The opening and closing of the AV valves is dependent on pressure differences between the atria and ventricles. ... This is due to the elevated pressures in the aorta and the pulmonary artery pushing the blood back toward the ventricles to close the semilunar valves.
