Which chambers of human heart contain oxygenated blood?

The deoxygenated blood is collected from different parts of the body and transported into the right atrium from which it moves to the right ventricle from where it is transported to the lungs for oxygenation. This oxygenated blood now comes to the left atrium and from here it is poured into the left ventricle. Therefore, the left part of the heart that is the left atrium and left ventricle contains the oxygenated blood.
