Total lung capacity depends upon:-: (A) Size of airway, (B) Closing volume, (C) Lung compliance, (D) Residual volume
Answer is C. TLC is the maximum volume to which the lungs can be expanded with the greatest possible effo. TLC = VC + RV (VC = IRV + TV + ERV) The expansion of lungs depends on its compliance Def: the extent to which lungs will expand for each unit increase in Transpulmonary pressure is k/a lung compliance.
