ANATOMY

Detailed explanation-1: -Tidal volume is the volume of air normally inspired or expired in one breath without any effort. It is about 500 ml in the average human adult male.

Detailed explanation-2: -Tidal volume (TV) measures the amount of air that is inspired and expired during a normal breath. On average, this volume is around one-half liter, which is a little less than the capacity of a 20-ounce drink bottle.

Detailed explanation-3: -The expiratory reserve volume (ERV), about 1, 200 mL, is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume.

Detailed explanation-4: -Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle. It measures around 500 mL in an average healthy adult male and approximately 400 mL in a healthy female.

Detailed explanation-5: -Tidal volume is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied. In a healthy, young human adult, tidal volume is approximately 500 mL per inspiration or 7 mL/kg of body mass.
