Question

Our lungs remove large amounts of $CO2$ approximately

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

Answer 1

The correct option is B $500mL/minute$

During the process of respiration, there is inhalation of oxygen and exhalation of carbon dioxide. here, a capacity which is almost equal in both the process of inhalation as well as exhalation is measured. It was found out that the normal healthy person can inhale or exhale about 500mL/minute. This capacity is called tidal volume (TV).

So, the correct option is '500mL/minute'.
