Question

following a normal inspiration, the volume of additional air that enters the lungs during forced maximal inspiration is called the
multiple choice
expiratory reserve volume
vital capacity
tidal volume
inspiratory reserve volume

Explanation:

• Expiratory reserve volume: It is the additional air that can be exhaled after a normal exhalation, not related to forced maximal inspiration.
• Vital capacity: It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. It is not the specific volume described in the question.
• Tidal volume: It is the volume of air that is normally inhaled or exhaled during quiet breathing, not the additional air during forced maximal inspiration.
• Inspiratory reserve volume: This is the volume of additional air that can be inhaled into the lungs during forced maximal inspiration after a normal inspiration.

Answer:

Inspiratory reserve volume
