The walls of alveoli are coated with a thin film of water & this creates a potential problem.Water molecules, including those on the alveolar walls, are more attracted to each other than to air, and this attraction creates a force called surface tension.This surface tension increases as water molecules come closer together, which is what happens when we exhale & our alveoli become smaller. Epithelial Tissue. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. Two forms occur in the human body: Covering and lining epithelium- forms the outer layer of the skin; lines open cavities of the digestive and respiratory systems; covers the walls of organs of the closed ventral body cavity.; Glandular epithelium- surrounds glands within the body Furthermore, this method enables measurement of the surface area deposition in the other regions of the human respiratory tract as well. Measuring the size distribution can give important information about the role of different particle types in the respiratory deposition, and thus give information on the health effects of different particle types
