Options
- A5 mL
- B20 mL
- C4 mL
- D15 mL
Correct answer
C. 4 mL
Step-by-step solution
Under normal physiological conditions, every 100 mL of deoxygenated blood delivers approximately 4 mL of CO₂ to the alveoli. For comparison, every 100 mL of oxygenated blood delivers approximately 5 mL of O₂ to the tissues under normal physiological conditions. Answer: 4 mL
