The amount of air breathed in and out during a normal respiration by human lungs is referred to as

The amount of air breathed in and out during normal, quiet respiration is defined as the tidal volume (TV) [2]. In a healthy adult, this volume is typically around 500 mL [2]. In contrast, vital capacity (VC) represents the maximum volume of air that can be exhaled after a maximal inhalation, encompassing the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. Inspiratory capacity refers to the total amount of air that can be inhaled starting from the end of a normal expiration [2]. Total lung capacity (TLC) is the maximum volume of air the lungs can hold after a forceful inhalation, including the residual volume that remains in the lungs even after maximal exhalation to prevent alveolar collapse [1]. Therefore, for normal breathing cycles, tidal volume is the correct physiological term.
