Question

what is the approximate tidal volume of an average adult human? 500 ml 1200 ml 2900 ml 5 liters

Explanation:

Tidal volume refers to the amount of air that is inhaled or exhaled during normal breathing. For an average adult human, it is approximately 500 ml. 1200 ml is close to the expiratory reserve volume (the additional air that can be forcefully exhaled after normal exhalation). 2900 ml is not a standard value for tidal - related volumes in normal adults. 5 liters is a much larger volume and not related to tidal volume.

Answer:

500 ml
