Why are respiratory diseases and disorders so life threatening?

Respiratory diseases and disorders are life-threatening primarily because they directly impair the body's ability to take in oxygen and expel carbon dioxide, which are vital for cellular function. Conditions like chronic obstructive pulmonary disease (COPD), Asthma, and pneumonia can lead to severe oxygen deprivation, causing organ failure and death if not treated promptly. Additionally, respiratory issues can exacerbate other health problems, complicating treatment and recovery. The lungs' intricate structure also makes them susceptible to infections and inflammation, further heightening the risk of life-threatening complications.
