What is "left atrium"?

The left atrium is one of the four chambers of the heart that receives oxygen-rich blood from the pulmonary veins and contracts to push the blood into the left ventricle for subsequent circulation throughout the body. It plays a vital role in systemic circulation and is essential for maintaining blood flow and oxygenation to the body's tissues and organs.
