MCQs on Breathing and Exchange of Gases: Class-XI for NEET Practice


Tidal Volume and Expiratory Reserve Volume of an athlete is 500 mL and 1000 mL respectively. What will be his Expiratory Capacity if the Residual Volume is 1200 mL?

NEET-2019 [Breathing-and-Exchange-of-Gases] [class-xi ]

  • 1700 mL
  • 2200 mL
  • 2700 mL
  • 1500 mL
    • Correct Option: D  [ 1500 mL ]

    Remark:

Match List I with List II:

List-I List-II
(A)Expiratory capacity (I)Expiratory reserve volume + Tidal volume + Inspiratory reserve volume
(B)Functional residual capacity (II)Tidal volume + Expiratory reserve volume
(C)Vital capacity (III)Tidal volume + Inspiratory reserve volume
(D)Inspiratory capacity (IV)Expiratory reserve volume + Residual volume
Choose the correct answer from the options given below:
