Follow the red blood cell as it
travels from the lungs to typical body cells (e.g. muscle).
- The oxygen rich, high pH environment
of the lungs, causes Hemoglobin to release 4 CO2 molecules and pick up 4 O2
- The CO2 produced by the muscle
cell during metabolism lowers the blood pH, the blood becomes more acidic.
- The high CO2 content and low pH
causes Hemoglobin to release the 4 O2s, which diffuses into the cell.
- The 4 CO2s now binds with the
Hemoglobin and rides it back to the lungs and out of the body.
