upper right chamber
Right Atrium
receives deoxygenated blood from the body
Right Atrium
lower right chamber
Right Ventricle
receives the blood from the right atrium and pumps it into the pulmonary artery
Right Ventricle
upper left chamber
Left Atrium
receives oxygenated blood from the lungs and pumps it into the left ventricle
