Blood returning from the body (systemic circulation) enters which chamber of the heart?

OpenStudy (compassionate):

The "dirty" blood comes back to the heart via the veins(superior vena cava and inferior vena cava) to the right atrium. From there, it is pumped into the right ventricle. From there it is pumped towards the lungs to get oxygenated and "clean" blood now makes its way back to the left atrium which pumps in into the left ventricle. It is then pumped out to the body via the aorta.
