Question

The volume of air within stiff, cartilaginous conduits of a respiratory system that are devoid of respiratory epithelium, like the trachea and bronchi, is classified as ____________.

A.) pleural pressure
B.) tidal volume
C.) anatomical dead space
D.) additional surface areas for gas exchange
E.)vital capacity

Answer 1

The correct classification for the volume of air within the trachea and bronchi that does not participate in gas exchange is anatomical dead space.

Step-by-step explanation:

The volume of air within stiff, cartilaginous conduits of a respiratory system that are devoid of respiratory epithelium, like the trachea and bronchi, and does not participate in gas exchange is classified as anatomical dead space. This is the air in the respiratory system that does not reach the alveoli, where gas exchange occurs. This differs from alveolar dead space, which involves air that reaches alveoli that are not functioning properly due to disease or abnormal blood flow. It is important to distinguish anatomical dead space from other respiratory volumes like tidal volume (the amount of air that enters the lungs during quiet breathing) or vital capacity (the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume).
