When airway and breathing are compromised after an explosion, which organ is most likely the source of the respiratory disturbance?

• A. Brain
• B. Stomach
• C. Lungs
• D. Bones

Answer: (C)

Breathing disturbances after an explosion are most directly caused by injury to the lungs, because the lungs are the organ that handles air movement and gas exchange. The blast overpressure can damage lung tissue, causing alveolar rupture, contusions, edema, or pneumothorax, all of which disrupt ventilation and oxygenation. While the brain can influence breathing, and chest wall injuries (like broken ribs) can worsen breathing, the primary source of respiratory disturbance in this scenario is the lungs. Stomach injuries don’t affect breathing, and bones are not the organ responsible for gas exchange, so they’re less likely to be the source of the breathing problem.
