Question

Name factors that can shift the ISB deeper into the lungs.

A. Increased tidal volume
B. Decreased respiratory rate
C. Narrowing of airways
D. Shallow breathing

Answer 1

Increased tidal volume, narrowing of airways, and shallow breathing can shift the ISB deeper into the lungs.

Step-by-step explanation:

The factors that can shift the ISB (inspiratory breathing system) deeper into the lungs are:

A. Increased tidal volume: When the volume of air per breath increases, more air is drawn into the lungs which can push the ISB deeper.
C. Narrowing of airways: If the airways become narrower, it can force the air to flow deeper into the lungs.
D. Shallow breathing: When breathing becomes shallow, the air tends to fill the lower parts of the lungs, pushing the ISB deeper.
