Final answer:
The volume of air moved in and out of the lungs during normal respiration is referred to as tidal volume, which is approximately 500 milliliters for a quiet breath.
Step-by-step explanation:
The amount of air moved in and out of the lungs during a normal, quiet respiration is called tidal volume (TV). This is the volume of air that is inspired and expired with each breath during restful breathing. The tidal volume is different from other lung volumes, such as the inspiratory reserve volume (IRV), which is the additional air that can be inhaled after a normal inhalation, or the expiratory reserve volume (ERV), which is the extra air that can be forcibly exhaled after the end of a normal exhalation.
The total lung capacity (TLC) is the sum of all the lung volumes, including the tidal volume, residual volume, inspiratory reserve volume, and expiratory reserve volume. Anatomical dead space is the air in the respiratory tract that does not participate in gas exchange because it does not reach the alveoli.
