It occupies a central position in the thoracic cavity, lying slightly to the left of the midline. It receives oxygenated blood from the lungs and serves as a holding chamber for blood before it is pumped into the left ventricle.
The left atrium is approximately cube shaped and forms the base of the heart posteriorly. It has thicker muscular walls compared to the right atrium; however, the ventricular walls are significantly thicker.

Each atrium has a superficial flap-like extension called an auricle because its shape resembles the external ear of a human (Figure \(\PageIndex{8}\)). You may also hear them referred to as atrial appendages.
