The upper chambers of the heart, known as the right and left atria, receive blood in large vessels coming from the body and lungs.

The left lower ventricle or chamber is powerful and when the mitral valve fails at its job the left ventricles can easily force some of the blood backward back in the left upper atrium or chamber each time the heart beats.
