How alveoli collapse due to surface tension

[@frostyfeet0345]

@@masoomchokro7472Due to surface tension the tiny water molecules between the air and water shrinks the alveoli to small round structure
It further shrinks into smaller due to surface tension
This is prevented by surfactant.

[@Eyad_m_a_n]

[@mirsuhail15]

​​@@masoomchokro7472 The alveoli have got a thin film of water on their inner surface and the water molecules on the surface of the film experience a net inward pull due to unbalanced forces tending to acquire the shape of a sphere like rain drops, if allowed to do so the water film will try to have the least surface area (sphere) & will pull the inner surface of the alveoli from all directions tending to collapse it that's where a surfactant comes to rescue lowers the surface tension therefore lowering the tendency of the water film to collapse the alveoli

such a soothing voice wish my professor sounded like this instead of like Hagrid from Harry potter

[@011amarnathp3]

More helpful maam
In covid 19 - decrease surfactant as a result of which alveoli collapse.

[@medwizard702]

pls make more videos on respiration.

[@keerthikumar348]

Good job🤩

[@stepper3761]

Smooth

[@mansipratap1691]

U should tell how surfactant prevent collapse more deeply.. Btw thanks 🙂
