The Total Lung Capacity ( TLC ) is the total volume of air accomodated in the lungs at the end of a forced inspiration. This includes:
Options
- ARV ;   IC (Inspiratory Capacity); EC (Expiratory Capacity); and ERV
- BRV ; ERV ; IC and EC
- CRV ;   ERV ;   VC (Vital Capacity) and FRC (Functional Residual Capacity)
- DRV (Residual Volume); ERV (Expiratory Reserve Volume); TV (Tidal Volume); and IRV (Inspiratory Reserve Volume)
Correct answer
D. RV (Residual Volume); ERV (Expiratory Reserve Volume); TV (Tidal Volume); and IRV (Inspiratory Reserve Volume)
Step-by-step solution
Total Lung Capacity ( TLC ) : Total volume of air accommodated in the lungs at the end of a forced inspiration is called TLC . Mathematically, it can be represented as: TLC = RV + VC , But, VC = TV + ERV + IRV , Therefore, TLC = RV + TV + ERV + IRV
