a. Some texts show a lower percentage composition of nitrogen in expired air, suggesting that some nitrogen is used. This is not the case. The actual nitrogen content remains the same. However, since extra water vapour in expired air adds volume to total expired air, then the percentage composition of nitrogen works out to be less.
