Asphyxia primarily involves which organ?

Asphyxia primarily involves which organ?

• A. Lungs
• B. Heart
• C. Brain
• D. Kidneys

Answer: (A)

Gas exchange happens in the lungs, where oxygen enters the blood and carbon dioxide is removed. Asphyxia occurs when breathing is blocked or ineffective, so oxygen can't reach the blood properly. The lungs are the primary organ involved because the issue originates with oxygen uptake and carbon dioxide removal. The heart can still beat and circulate blood, but the blood remains poorly oxygenated; the brain and kidneys may suffer from the resulting lack of oxygen, but they are affected downstream rather than initiating the condition.
