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. 2  Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. 2  From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.
