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 atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins.
Detailed explanation-3: -On the right side of the heart, the right atrium and right ventricle work to pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated. On the left side of the heart, the left atrium and left ventricle combine to pump oxygenated blood back through the body.
