the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back

The structure and function of right atrium?
The right atrium is one of the four chambers of the heart that receives deoxygenated blood from the body through the superior and inferior vena cava.

The right atrium is lined with specialized cells that help regulate the heart's electrical activity and coordinate its contractions.
