WebAdditionally, there was a significant decrease of surface area of AE1 cells covered by air and an increase of surface area of intermediate cells covered by air. ... Intracellular surfactant is released into the airspace, where it is essential for reducing surface tension at the alveolar air–liquid interface at end-expiration, so that it ... WebAt fixed lung volume (VL), alterations in surface tension change alveolar surface area (S) and lung recoil (PL).

A lung that is less elastic will require less muscle action to perform adequate ventilation. ... The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly. Thus, the correct answer is option ... WebSurfactant dysfunction is a lung disorder that causes breathing problems. This condition results from abnormalities in the composition or function of surfactant, a mixture of certain fats (called phospholipids) and proteins that lines the lung tissue and makes breathing easy. Without normal surfactant, the tissue surrounding the air sacs in the ... fill gaps in eva foam
