1

5 ml of O₂ to the alveoli

2

4 ml of CO₂ to the alveoli

3

40 ml of CO₂ to the alveoli

4

50 ml of O₂ to the alveoli

Solution:

Deoxygenated blood transports carbon dioxide from the tissues to the lungs. Approximately 4 ml of CO₂ is transported by every 100 ml of deoxygenated blood. Therefore, 1000 ml of deoxygenated blood delivers approximately 40 ml of CO₂ to the alveoli for diffusion and exhalation.
