Alveolar Epithelial Injury

Alveolar epithelial injury involves damage to the thin cells lining the alveoli, the tiny air sacs in the lungs where oxygen transfer occurs. This damage can result from infections, toxins, or inflammation, impairing the alveoli's ability to exchange gases efficiently. Such injury can lead to fluid leakage, scarring, and reduced lung function, making it harder to breathe and get enough oxygen into the bloodstream. Recognizing and addressing alveolar epithelial injury is crucial in treating lung diseases like acute respiratory distress syndrome (ARDS) and other conditions affecting lung health.
