Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The right and left atria are the top chambers of the heart and receive blood into the heart. The right atrium receives deoxygenated blood from systemic circulation and the left atrium receives oxygenated blood from pulmonary circulation.
Detailed explanation-3: -The left atrium receives blood full of oxygen from the lungs and then empties the blood into the left ventricle.
