The maximum volume of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a forced inspiration is called:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) - VC.
Vital Capacity (VC) is the the maximum volume of air a person can breathe in after a forced expiration. This includes ERV, TV and IRV or the maximum volume of air a person can breathe out after a forced inspiration.
Residual Volume (RV) is the volume of air remaining in the lungs even after a forcible expiration. This averages 1100 mL to 1200 mL.
Total Lung Capacity (TLC) is the total volume of air accommodated in the lungs at the end of a forced inspiration. This includes RV, ERV, TV and IRV or vital capacity + residual volume.
Functional Residual Capacity (FRC) is the volume of air that will remain in the lungs after a normal expiration. This includes ERV+RV.
