Of course, as the alveoli are in the lungs, they must be very small to provide enough area for the exchange of gases. In fact, there are about 300 million alveoli in the adult lung. WebType II cells in the alveolar wall contain secretory organelles known as lamellar bodies that fuse with the cell membranes and secrete pulmonary surfactant. This surfactant is a film of fatty substances that reduce alveolar surface tension. Continuously released by exocytosis, the coating prevents the alveoli from collapse.
