Question

Our lungs remove large amounts of CO₂, approximately:

• A. 500 mL/minute
• B. 200 mL/minute
• C. 200 L/minute
• D. None of the above

Answer 1

The correct option is A

500 mL/minute

The correct option is A.

Explanation of the correct answer:

1. The volume of air inspired or expired during normal respiration is defined as the tidal volume.
2. The average tidal volume of a healthy human being is 500mL/min.
3. Thus, the amount of carbon-di-oxide given out is 500mL/min.

Explanation of the incorrect options:

Option B:

The amount of carbon-di-oxide given out is 500mL/min. Thus, this option is incorrect.

Option C:

The amount of carbon-di-oxide given out is 500mL/min. Thus, this option is incorrect.

Option D:

The amount of carbon-di-oxide given out is 500mL/min. Thus, this option is incorrect.

Final answer: The amount of carbon-di-oxide given out is 500mL/min.
