It receives oxygenated blood from the pulmonary veins and passes it to the left ventricle through the mitral valve. It is discussed in cardiovascular physiology, echocardiography interpretation, and structural heart disease. It is commonly referenced in atrial fibrillation care, valvular disease assessment, and heart failure evaluation."}
