What is Total Lung Capacity?
Options
- ATotal volume of air accommodated in the lungs at the end of a forced inspiration
- BThe maximum volume of air a person can breathe out after a forced inspiration
- CThe maximum volume of air a person can breathe in after a forced expiration
- DTotal volume of air accommodated in the lungs at the end of a normal expiration
Correct answer
A. Total volume of air accommodated in the lungs at the end of a forced inspiration
Step-by-step solution
Inspiratory Capacity (IC): Total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume ( TV+IRV). Expiratory Capacity (EC): Total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV+ERV). Functional Residual Capacity (FRC): Volume of air that will remain in the lungs after a normal expiration. This includes ERV+RV. Vital Capacity (VC): The maximum volume of air a person can breath
