Why can CO/CO2 easily block out O2 of the blood cells, and not opposite?
That makes sense. But why doesn't oxygen do the same thing to carbon monoxide and dioxide in the blood?
Oxygen actually does have a weak affinity for carbon monoxide and carbon dioxide, but the affinity is much weaker than the bond that carbon monoxide and dioxide have with hemoglobin. Additionally, oxygen in the blood is typically present at a much higher concentration than carbon monoxide and dioxide, which makes it more likely that it will bind to hemoglobin instead of the carbon molecules.
