Verified step by step guidance

Step 1: Understand the concept of respiratory volumes. Respiratory volumes are measurements of the amount of air exchanged during different phases of breathing. These include tidal volume, inspiratory reserve volume, residual volume, and vital capacity.

Step 2: Define tidal volume. Tidal volume refers to the amount of air inhaled or exhaled during normal, quiet breathing. It is the baseline volume of air moved in and out of the lungs without any extra effort.

Step 3: Compare tidal volume with other respiratory volumes. Inspiratory reserve volume is the additional air that can be inhaled after a normal inhalation. Residual volume is the air remaining in the lungs after a forceful exhalation. Vital capacity is the total amount of air that can be exhaled after a maximum inhalation.

Step 4: Recognize that tidal volume is specifically associated with normal, quiet breathing, making it distinct from the other terms listed.

Step 5: Conclude that the term describing the respiratory volume inhaled or exhaled during normal, quiet breathing is 'tidal volume,' based on its definition and comparison with other respiratory volumes.
