Understand the definitions of the terms provided in the question: Tidal volume, Residual volume, Inspiratory reserve volume, and Vital capacity.
Tidal volume refers to the volume of air inhaled or exhaled during a normal, resting breath. This is the key term to focus on for this question.
Residual volume is the amount of air remaining in the lungs after a forceful exhalation. It does not describe air exchanged during normal breathing.
Inspiratory reserve volume is the additional air that can be inhaled after a normal inhalation, which is beyond the resting breath volume.
Vital capacity is the total amount of air that can be exhaled after a maximum inhalation, combining multiple volumes (tidal volume, inspiratory reserve volume, and expiratory reserve volume). It is not specific to resting conditions.
