Is a pumping chamber of the heart, of which there are two: the right, which pumps blood into the lungs, and the left, which pumps blood to the body.

The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs where they are oxygenated.

Hope this helped :)
Have a great day
