Question

If the thoracic wall but not lungs is punctured.

• A. The lungs get inflated
• B. The man dies as the lungs get collapsed
• C. The breathing rate decreases
• D. The breathing rate increases

Answer 1

The correct option is B The man dies as the lungs get collapsed

The puncture in thoracic wall, would mean the wound to the pleural/chest wall, as it is defined so for its function of respiration. This would eventually lead to the damage of pleural membrane which in turn would disrupt the pressure balance of gases, which would lead to the collapsing of the lungs. Thus, the man would eventually die. Thus, Option B is correct.
