In a healthy heart, oxygen-rich blood moves from your lungs to the left upper chamber of your heart. The upper chambers are called your atria. Your atria pump the blood into the two lower chambers of your heart, known as your ventricles. Blood from your lungs is pumped from the left atrium into the left ventricle. The left ventricle pumps your blood around your body and back to the right atrium, the right ventricle, and then your lungs.
