Explanation:
Detailed explanation-1: -Reoxygenated blood (red blood) leaving the lungs enters the heart through the pulmonary veins and is carried into the left atrium. The reoxygenated blood then flows through the mitral valve and into the left ventricle. The mitral valve closes after the blood passes through to prevent backflow.
Detailed explanation-2: -The aortic valve controls the flow of blood out from the heart to the rest of the body.
