Question

question 8
which of the following structures is considered anatomic \dead space\?
a alveolus
b respiratory bronchiole
c trachea
d terminal bronchiole

Explanation:

Anatomic dead space refers to the volume of air in the conducting airways (such as the trachea, bronchi, and bronchioles that are not involved in gas exchange). Alveoli (A) and respiratory bronchioles (B) are involved in gas exchange. Terminal bronchioles (D) are part of the conducting zone but are not the main anatomic dead - space structure. The trachea (C) is a major part of the conducting airways which do not participate in gas exchange and thus is considered anatomic dead space.

Answer:

C. Trachea
