Pathway of an Oxygen Molecule as it Travels Through the Human Body
STEP |
ORDER 1-12 (1 is entry into the Body and 12 is used in the Cell) |
COLOUR Pink for the respiratory system Blue for the circulatory system Green for the digestive system |
✓ where active transport occur. ★ where passive transport occurs |
enters increasingly smaller branched bronchioles |
|||
transported by the blood to an artery |
|||
enters the mitochondria and is used in cellular respiration reactions to produce ATP |
|||
inhaled through the nose |
|||
enters an alveolus |
|||
enters a body cell |
|||
enters into a capillary |
|||
dissolves in liquid on the surface of the alveolus |
|||
moves from the artery into a capillary at the site of a body cell |
|||
enters trachea |
|||
enters either left or right bronchus |
|||
passes through pharynx and then larynx |

The figure shows the pathway of an oxygen molecule as it travels through the human body. All the processes involved in oxygen transport are passive processes and donot require ATP. Oxygen tranport across membranes occurs by simple diffusion, which is a passive transport.
