How is oxygen moved from the lungs to the blood?

When oxygen reaches the alveoli of the lunngs, it diffuses into the blood. The oxygen enters the red blood cells and combines with the haemoglobin to form oxyhaemoglobin. When the red blood cells reach the tissue, the oxyhaemoglobin disassociates, releasing oxygen which diffuses into the tissue cells.
