WebNov 10, 2024 · The alveoli cover a surface of more than 1,399 feet (ft) or 130 square meters (m2). This large surface area is necessary to process the huge amounts of air involved in breathing and getting... WebSurface tension is the property, resulting from molecular forces, that exists in the surface film of all liquids and tends to contract the volume into a form with the least surface area; the particles in the surface are inwardly attracted, thus resulting in tension. Surface tension is nearly zero in the fluid-filled lung. The alveoli of the ... WebSurface tension exists because the oppositely charged ends of water molecules are attracted to each other . As the water molecules pull together, they also pull on the alveolar walls, causing the alveoli to recoil and become smaller. Two factors keep the lungs from collapsing: (1) surfactant and (2) pressure in the pleural cavity. Surfactant cowes day spa
