The transportation of oxygen to different parts of the body is achieved through the Red Blood Cells.
Human beings breathe in air through their nostrils.
This air goes into the lungs where the oxygen is replaced with the carbon dioxide available in the lungs.
This oxygen is then infused in the blood which then carries the oxygen rich blood to various parts of the body.
