Final answer:
The anatomic dead space is true because there is no exchange of gases between the air in these spaces and the blood.
Step-by-step explanation:
The anatomic dead space is so called because there is no exchange of gases between the air in these spaces and the blood. This is true.
Anatomic dead space refers to the air that is present in the airway but never reaches the alveoli where gas exchange occurs. This dead space is important for the overall functioning of the respiratory system, as it helps to condition the air and humidify it before it reaches the alveoli.
