Despite appropriate care, the patient dies. At autopsy, examination of the lungs shows enlargement of the airspaces in the respiratory bronchioles and alveoli. Destruction of which of the following cells is the most likely cause of these findings?? A: Non-ciliated cuboidal cells, B: Type I pneumocytes, C: Type II pneumocytes, D: Ciliated cuboidal cells, E: Ciliated columnar cells,  <response>: This is a question about alpha-1-antitrypsin deficiency, which causes destruction of lung tissue and enlargement of airspaces. The question is asking which cell type is most affected in this condition. Based on the description of enlargement of respiratory bronchioles and alveoli, this points to a problem with the alveolar epithelium. The two main cell types here are type I and type II pneumocytes. Type I pneumocytes are thin squamous cells important for gas exchange. Damage to these cells would cause the airspace enlargement described.B: Type I pneumocytes
