NettetThe relatively low solubility of oxygen necessitates the large internal surface area and very thin walls of the alveoli. The cytoplasm in the thin portion contains pinocytotic vesicles which may play a role in the removal of small particulate contaminants from the … NettetThe alveolar septum or wall consists of three components: epithelium (which lines the alveolus or air space), interstitium, and capillary endothelium. Gas exchange occurs in the alveoli across the thin epithelial lining and adjacent endothelium (air–blood barrier).
