Left Atrium

The left atrium is one of the heart's four hollow chambers; it can be found on the upper right hand side of the heart. Oxygen-rich blood enters the left atrium from the pulmonary veins; the left atrium then pumps this blood directly into the left ventricle. The left atrium receives most of its blood supply from the left circumflex coronary artery. Drainage of the veins is carried out, in part, through left atrium's oblique vein.
