Answer 2

Option 3 is the right answer. Rebreathing of expired air causes a decrease in arterial pH

• As we re-breath, the partial pressure of carbon dioxide increases in the blood.
• Carbon dioxide is an acidic oxide.
• As the partial pressure of carbon dioxide increases in the blood, it becomes more acidic.
• That is the arterial pH will decrease.
• The lower the pH, the more acidic the blood.
• This leads to an increase in alveolar respiration.
