Total Lung Capacity (TLC) is equal to:
- A.VC + RV
- B.IC + ERV
- C.EC + IRV
- D.All of the aboveCorrect answer
Solution
Total Lung Capacity (TLC) is the total volume of air accommodated in the lungs at the end of a forced inspiration. TLC = Vital Capacity (VC) + Residual Volume (RV). Since VC = IC + ERV, TLC also equals IC + ERV + RV, and since EC = TV + ERV, TLC equals EC + IRV + RV. Thus, all given options represent TLC equations.
