Final answer:
The space that is not part of the anatomical dead space is the terminal bronchiole.
Step-by-step explanation:
The space that is NOT part of the anatomical dead space is the terminal bronchiole.
The anatomical dead space refers to the air space within the respiratory system that never reaches the alveoli and does not participate in gas exchange. In this case, the bronchioles, trachea, bronchi, and respiratory bronchioles are all part of the anatomical dead space except for the terminal bronchiole.
The terminal bronchiole is the final branch of the bronchioles before the structures of gas exchange, such as the alveoli, begin. It is here where gas exchange occurs, making it an important part of the respiratory system.
