What is vital capacity of our lungs?

Options

  1. ATotal lungs capacity minus residual volume
  2. BInspiratory reserve volume plus tidal volume
  3. CTotal lungs capacity minus expiratory reserve volume
  4. DInspiratory reserve volume plus expiratory reserve volume

Correct answer

A. Total lungs capacity minus residual volume

Step-by-step solution

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