The termination point for bronchioles, FTP, name these small cup-shaped sacs of the lungs, the site of diffusion of oxygen into the bloodstream.
These microstructures are normally guarded from damage from neutrophil elastase buildup by the protein alpha-1 antitrypsin. Adhesive atelectasis is caused by underproduction of surfactant by their * Type II cells. Cytoplasmic extensions of their type I cells form their epithelium, which separates them from the capillary endothelium and allows their primary function.
