Q159 / 199 · NEET 2008 (Mains) · Zoology

What is vital capacity of our lungs?

  • Correct answer
    A
    Total lungs capacity minus residual volume
  • B
    Inspiratory reserve volume plus tidal volume
  • C
    Total lungs capacity minus expiratory reserve volume
  • D
    Inspiratory reserve volume plus expiratory reserve volume

Solution

Vital capacity $=T V+I R V+E R V$ Total lung capacity $=\mathrm{VC}+\mathrm{RV}$ So we can say that $\mathrm{VC}=$ Total lung capacity - Residual volume.

Hence, the correct answer is option: 'A'.
