best video on youtube on surfactant
Wow, this makes much more sense! Thank you!
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!
A really nice animation and an excellent explanation, thank you 💛👌🏾
Always great videos! Thank you so much !
Crisp and clear.... Thank you and god bless you... Love from India
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 !!!!
Thank you so much. It helps me as an aquatic veterinarian to remind again about surface tension and surfactant related with swimming bladder 😁
best surfactant video right here
brilliant, simple, well explained
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 ❤️
The best explanation ever
What an explaination ♥️♥️♥️
Thank you sister. Great explanation
Best video on surfactant👌 Awesome 💯
Thank you so…You are such a lifesaver 😭
Thank you for the great explanation ❤
This is excellent! Thank you
thanks for such a nice elaborative manner of lecture
thanks alot
you are live saving, thanxxxxxx
what an amazing video thanks alot
Simply superb ❤️
Amazing explanation and animation. Among all of medical channels you are one of the best.
Thank you very much!😊
Thank you sm for including the Laplace equation, it solidifed understanding for some of us who like to think in numeric relationships, lol
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.
Fr
@@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
Easy and short ❤❤❤thank you
That was GREAT!!!!!!
Really awesome maam,plz make more videos they r really helpful..tq much
Wow beautiful teaching
Clear and explicit
i loved this thank you
Top notch video
U made it easy dear❤️
thank you so much madame
Thank you such a good video, you deserve moree views
Awesome 👍👍
Thanks alot❤
Amazing
Wonderful help me a lot thanks dear .keep making good videos about science and please few for biotechnology ❤
Thank you
Thank you💚
Very nice mam
wowww thank uuu!!
Thankuuuu... I hate physiology but u made it easy 💜
thank you soo much
Love from India💕💜
Thannnk u awsome. 💜🔥
you’re the best
Super awesome
Good job🤩
excellent
Underrated💕
pls make more videos on respiration.
More helpful maam
In covid 19 - decrease surfactant as a result of which alveoli collapse.
great explanation..
subscribed 🙌
Thank you!
Excellent and succinct +++
Thank you!😊
verrrrry goooooood
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
Smooth
awesome
Thank you! I hope they're helping. 😊
👍👍👍
🙏🙏🙏🙏
❤
👀❤️🔥
Alveli functional unit of lungs or nephron ??
Thank you because this topic is definitely irritating lol
