When using the term auricle in terms of biology, there are two possible things you could be talking about. One is the external portion of the human ear, and the other is a part of the heart. Since you are specifically are talking about the right auricle, that leads me to believe that you must be referring to the heart since it has four different basic chambers.
The right auricle is really an older term...

The right auricle is really an older term for the right atrium. As I stated earlier, the human heat has four basic chambers, the left and right atria and the left and right ventricles. The atria (plural for atrium) are the top two chambers of the heart and the ventricles are the lower two chambers of the heart. The right atrium (auricle) is the chamber where incoming blood from the major vein of the circulatory system (vena cava) brings deoxygenated blood into the heart. The right atrium (auricle) receives the blood and pushes it into the the right ventricle, which then transports the blood to the lungs for oxygenation. The freshly oxygenated blood then is pumped through the left side of the heart (atrium and ventricle) before it re-enters the circulatory system to bring oxygen to the rest of the body.
