Listed below are four respiratory capacities (a-d) and four jumbled respiratory volumes of a normal human adult Respiratory capacities (a) Residual volume (b) Vital capacity (c) Inspiratory reserve volume (d) Inspiratory capacity Respiratory volumes 2500 mL 3500 mL 1200 mL 4500 mL Which one of the following is the correct matching of two capacities and volumes

Answer: (2)

Solution

From NCERT, the normal values for an adult human are: residual volume (RV) about 1100-1200 mL; inspiratory reserve volume (IRV) 2500-3000 mL; tidal volume about 500 mL; expiratory reserve volume (ERV) 1000-1100 mL. Inspiratory capacity (IC) = TV + IRV, about 3500 mL; vital capacity (VC) = ERV + TV + IRV, about
