Example Question #7 : Understanding Respiratory Functions
What is tidal volume?
Possible Answers:
The total volume of the lungs
The largest volume of air that can enter the lungs after forceful inhalation
The volume of air still in the lungs after forceful exhalation
The largest possible volume of air an animal can move in and out of its lungs
The volume of air that flows in and out of the lungs during relaxed breathing
Correct answer:
The volume of air that flows in and out of the lungs during relaxed breathing
Explanation:
Tidal volume is nominally and conceptually similar to an ocean tide. Under calm conditions, a tide is not particularly extreme at either its low or high points. During normal, relaxed respiration, an animal breathes in and out moderate volumes of air, creating its tidal volume.
