Question

how do we calculate the vital capacity?
multiple choice
add expiratory and inspiratory reserve volume.
divide tidal volume by total lung volume.
add expiratory and inspiratory reserve volume and the tidal volume.
subtract tidal volume from the sum of expiratory and inspiratory reserve volume.

Explanation:

Vital capacity is calculated by adding the expiratory reserve volume, inspiratory reserve volume, and tidal volume. This is a fundamental concept in respiratory physiology.

Answer:

Add expiratory and inspiratory reserve volume and the tidal volume.
