Question
15 out of 15
 

Vital capacity is



A Tidal volume + Expiratory Reserve Volume

B Tidal volume + Inspiratory Reserve Volume

C I.R.V. + E. R.V.

D T.V. + I.R.V. + E.R.V.

E Tidal volume

Ans. D T.V. + I.R.V. + E.R.V.

See the figure:-

Lungs capacities

(a) VC = IRV + TV + ERV Q IC = IRV + TV Q

VC=IC+ERV Q FRC = ERV + RV Q

(b) TLC=IRV +TV +ERV +RV Q

or = IC + FRV Q

or=VC +RV Q
