Zoology - Breathing and Exchange of Gases Question with Solution | TestHub
What will be the additional volume of air that a person can expire by a forcible expiration?
Options:
Answer:
Solution:
Expiratory Reserve Volume : (ERV = 1000 mL to 1100 mL) - It is an additional volume of air that a person can expire by a forcible expiration.
Tidal Volume (TV = 500 mL) - It is the volume of air inspired or expired during normal respiration.
Inspiratory Reserve Volume (IRV = 2500 mL to 3000 mL) It is an additional volume of air that a person can inspire by a forcible inspiration.
Residual Volume (RV = 1100 mL to 1200 mL) - It is the volume of air remaining in the lungs even after a forcible expiration.
Functional Residual Capacity (FRC = ERV + RV) - It refers to the volume of air that remains in the lungs after a normal expiration.
Vital Capacity (VC = ERV + TV + IRV) - It is the maximum volume of air that a person can inspire after forced expiration.
Total Lung Capacity (TLC = ERV+TV+IRV+RV = VC+RV) - It refers to the total volume of air that can be accommodated in the lungs at the end of forced inspiration.
