Is There a Limit on the Transfer of Oxygen Between the Lungs?

rob, when i was proposing this thought, you gave me some looks. So i need to throw this back. And i jumped, i just gave you the finger because we're glaring at each other behind our microphones right now. For one listening, essentially, if we look at the amount of oxygen in the blood, it's relatively constant throughout all ranges of exercise. Only in the highest level athletes,. working at a maximum, maximam work load, do we ever really see that oxygen drop significantly.
