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: -Your lungs add oxygen to your blood. The oxygen-rich blood returns to your heart through the pulmonary veins. Visit our How the Lungs Work page to learn more about what happens to the blood in the lungs. The oxygen-rich blood from the lungs then enters the left atrium and is pumped to the left ventricle.
Detailed explanation-3: -The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
Detailed explanation-4: -Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Detailed explanation-5: -The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.
