In this article. Interstitial lung disease is a general category that includes many different lung conditions. All interstitial lung diseases affect the interstitium, a part of the lungs ' anatomic structure. The interstitium is a lace-like network of tissue that extends throughout both lungs.
Diseases of the Lungs. 1  Emphysema --destruction of alveoli reduces surface area for gas exchange. 2  Fibrotic lung disease --thickened alveolar membrane slows gas exchange, loss of lung compliance. 3  Pulmonary edema --fluid in interstitial space increases diffusion distance.
