I just answered this for someone else, so I'm just going to paste the same answer here:

Blood enters the right atrium from two major veins: the Superior Vena Cava which brings blood from the upper body and the Inferior Vena Cava that brings blood from the lower body. This blood is low in oxygen and therefore bluish in color. The blood then goes to the right ventricle and from there goes to the lungs where they CO2 is released and O2 taken into the blood.

The blood then returns to the heart into the left atrium. From here it is pumped into the left ventricle and then out through the aorta. From here it takes all the branches of arteries to supply O2 to the cells all over the body.
