alleryVital capacity of the lungs is the sum of
ATV + IRV
BTV + IRV + ERV
CTV + ERV + RV
DTV + IRV + ERV + RV
Answer & Solution
Correct answer: B. TV + IRV + ERV
VC = TV + IRV + ERV — the maximum air you can expel after the deepest possible inhalation.
~4600 mL in a healthy adult.
Total lung capacity includes residual volume too (≈ 5800 mL).
