Alveoli: Structure, Function, and Disorders of the Lungs

Webalveoli to want to resist distension and cling together. While this force can aid in exhalation, this surface tension raises the pressure of the alveolar air and there is risk that surface tension could push the air out and cause the alveoli to collapse. Additionally, some of the alveoli are larger and some are smaller. WebIn the same zone, as you know, the alveoli here are extended by the low (more negative) intrapleural pressure at the apex. These extended alveoli tend to compress the surrounding capillaries, and the lack of arterial pressure to push past the extended alveolus means blood flow through capillary beds in zone 1 may be relatively low. long point national wildlife area ontarioWebSep 13, 2024 · Therefore, the presence of PFC gas in alveoli at end-expiration not only prevents alveolar collapse easing re-inflation, ...

"WebFunction. Pulmonary alveoli, where gas exchange occurs, are bubble-shaped and have a high degree of curvature. The surface tension of the moist inner surface is due to the attraction between the molecules in the alveolar fluid and tends to make the alveoli contract. Unchecked, this tendency would result in lung collapse. " - Collapse of the alveoli is known as
