lungs
Oxygen enters the blood stream through the air sacs in you lungs.

The lungs, I the alviolies.
Blood low in oxygen enters the right atrium of the heart through the superior and inferior vena cava.
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.
