Does the right atrium in the body contain oxygenated or dexoygenated blood?
The right atrium receives deoxygenated blood, then the blood
moves into the right ventricle. So both of them receive
deoxygenated blood. Once the blood returns from the lungs it is
oxygenated and comes into the heart through the pulmonary veins
into the left atrium then to the left ventricle then out to the
body.
