Answer 31

Negative pressure is created inside the lungs.

Question 32

When compensation for increasing oxygen demand fails and the​ body’s metabolic needs are not​ met, hypoxia becomes​ profound, carbon dioxide builds to dangerous​ levels, and the muscles used for increased respiration begin to tire. This state is​ called:

Answer 32

respiratory failure.
