best video on youtube on surfactant
Wonderful explanation and animation!I was facing difficulty to understand Surface Tension and Surfactant but after watching this video,my concept has cleared!Thank you very much! Have a good job!Stay blessed!

Wow, this makes much more sense! Thank you!
Perfect explanation, thank you! I've finally got the tension concept
This video is soo easy to follow that even a child could probably understand this. Thank you so muchhhh!!!!

How alveoli collapse due to surface tension

@@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.

@@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
Crisp and clear.... Thank you and god bless you... Love from India
A really nice animation and an excellent explanation, thank you 💛👌🏾
Thank you so much. It helps me as an aquatic veterinarian to remind again about surface tension and surfactant related with swimming bladder 😁
Always great videos! Thank you so much !
One of the best lecture in very short time .
So crisp, clear and easy way of teaching concepts... Loved the video... Even more, loved your voice ❤️
Best video I could find on the topic, thank you!
Well done ..nice summarize very helpful. Thank you
This was extremely helpful!! Thanks!
Great content !! UNDERATED !!!!
The best explanation ever
Amazing explanation and animation. Among all of medical channels you are one of the best.

Thank you sister. Great explanation
Best video on surfactant👌 Awesome 💯
Thank you sm for including the Laplace equation, it solidifed understanding for some of us who like to think in numeric relationships, lol
best surfactant video right here
brilliant, simple, well explained
thanks for such a nice elaborative manner of lecture thanks alot
Thank you for the great explanation ❤
This is excellent! Thank you
What an explaination ♥️♥️♥️

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

pls make more videos on respiration.
Good job🤩
excellent
U should tell how surfactant prevent collapse more deeply.. Btw thanks 🙂
such a soothing voice wish my professor sounded like this instead of like Hagrid from Harry potter
verrrrry goooooood
awesome
