Which term describes the combined amount of air that can be inhaled above tidal volume?

Explanation:
The main idea here is distinguishing lung volumes and what each one represents. The air you normally breathe in and out is the tidal volume. The extra air you can inhale beyond that normal breath is inspiratory reserve volume. So the term that describes the amount of air that can be inhaled above tidal volume is inspiratory reserve volume. Expiratory reserve volume, by contrast, is the extra air you can exhale beyond a normal expiration, not inhaled air. The combination of inspiratory and expiratory reserve volumes isn’t used to describe a single inhaled quantity; instead, vital capacity combines IRV, ERV, and tidal volume.
