Question

what is inspiratory capacity?
maximum amount of air that can be inhaled after a forced exhale
maximum amount of air that can be exhaled after a normal inhale
maximum amount of air that can be inhaled after a normal exhale
amount of air inhaled during a normal breath
amount of air exhaled during a normal breath

Explanation:

Inspiratory capacity (IC) is defined as the maximum amount of air that can be inhaled after a normal exhalation. It is calculated as the sum of tidal volume (TV) and inspiratory reserve volume (IRV).

• The first option describes vital capacity (VC) which is the maximum amount of air that can be exhaled after a forced inhalation (or maximum amount of air that can be inhaled after a forced exhalation).
• The second option is not a standard respiratory volume/capacity term.
• The fourth option is tidal volume (TV).
• The fifth option is also tidal volume (TV) but during exhalation.

Answer:

Maximum amount of air that can be inhaled after a normal exhalation
