Most common sit of injury of interstitial lung disease
Alveolar capillary interface
What are the types of parenchymal disease

Neonatal RDS
Premature infants have a deficiency in surfactant causing increase in surface tension and alveoli collapse & unable to perform appropriate gas transfer
Adult respiratory distress syndrome (ARDS)

DADS with damage to either alveolar epi cells or endo cells
(Formation of hyaline membranes) injury to ventilation or perfusion interface
Hallmark if ARDS
Hyaline membranes
