I would really like to express my admiration to the neatness of your work . This explanation is exactly what I was looking for long time ago !! but unfortunately DID NOT click into my head like the way you did . keep up the good work and thank you very much again .
Video's like this take concepts that are not actually complicated, but a little difficult to comprehend from just reading for some people and make them seem much more simple! Thank you!
Wow!! I've never understood surface tension in a more simplified manner than what you've just made me understand..... Thank You so much for your efforts and for giving your precious time in these lectures.... You are an Angel on earth.... :)
You forgot to say how surfactant help alveoli from collapsing. It is in my physics book. They basically talk about how there are many size of alveoli. Pressure is indirectly related to radius of the bubble(alveoli) and directly related with surface tension of the bubble, which basically means that bigger bubble has low pressure than smaller bubble and also high surface tension means high pressure . Basically as small alveoli has greater pressure, air from it will move to lower pressure big bubbles, collapsing smaller bubble due to difference in pressure(diffusion occurs). Surfactant reduces surfaces tension. Thus less difference in pressure.
Wow, just awesome! Thanks for really breaking it down and making it easy to understand. I am in dental school, and you explained it 100x better than my PhD professor!
I've had difficulties understanding this subject and everything related to respiratory system throughout my school years and into college.. Its only now that I understand it clearly . thanks alot 2020'8'22
I hope you're a lecturer at a top tier University, your delivery is just as good if not better than most of my lecturers are the University of Edinburgh
The systolic pressure in a major artery is measured at 115 mmHg. What is the net force on a 1 cm2 section of the arterial wall if the (absolute) pressure in the tissue outside the arterial wall is 109 kPa? (Patm = 101.3 kPa)
it is true that they help in expantion but how they help in preventing constricting because if we remove surface tention from water baloon its wall will constrict and baloon will break.
In your previous videos, I thought you said when we inhale the alveoli decrease its size. Now you're saying that alveoli expand when we inhale? I'm confused...I love your videos!!
A patient is presented with pneumonia type symptoms except mucus is watery... It's water, clear and not thick. We have exhausted all options of antibiotics. Patient currently given corticosteroids as a last ditch and is on a mechanical ventilator with oxygen levels of 70%. She has reactive type 2 pneumocytes. Ps: I am not a nurse... I am a concerned daughter looking for answers and hope as our medical system is primitive and they don't know what reactive type 2 is. Can anyone help please. Are there any other ideas we can try? Would proning help relieve any pressure on her lungs Thanks in advance. From New Zealand.

Finally something that makes sense, thanks a million!
+Farhana Ahmed you're welcome! :)
I always come to your lectures when I really want to understand something...thanks so much for your videos :)
+Margaret you're welcome Margaret! :)
Margaret
You're right
You are such a talent I have never met in a million years. Wawooo. Thanks so way so much . Clearly understood everthing

Erin Blair Thats wonderful to hear Erin :)
I love how he repeats himself to ensure you get the message
The only lecture I have found useful! Thank you!
Thank you so much! I have been looking for this explanation for years now. You are awesome with details. Thank you again.
You are the only one make me understand this surface tension.
Thanks my teacher ❤️

You make what seems hard, easy .. thank you
Malek Ahmaro :-) you're very welcome!
time and effort saved !!! norwegian guy thanks u !!!
OMG! This totally makes sense! Thank you so much for sharing your knowledge!
Rachel Park You're welcome Rachel!

I understood the whole subject within the first 7 mins! you have a talent of teaching :)
Thanks :)
I honestly love you AK
Thank you very much, I always follow my lessons through your channel. I follow you from Jordan and admire your lessons.
So informative are your lectures, thumbs up
you reallly explain good , thank you
Brilliant!!! Well explained
Love your lectures! the way you explain everything is wonderful and you make everything make sense. Thank you so much
So much hard work he put to make us understand the difficult topic in a simple way... thank you..God bless 😊
Your videos are exceptional!
Thank u so much sir for great efforts and explanation.
From India
Unstoppable. Thank you, great work!
Very.....very nice lecture . Now I understand full about surfactant. Thanks sir ...God bless you
Deljinder Singh you're welcome! and thanks :)
I hope you're a lecturer at a top tier University, your delivery is just as good if not better than most of my lecturers are the University of Edinburgh
I've been trying to understand this and you have made it so much clearer. Thank you :)
Nice teaching as always
now i understand what surfactant is . thanks so much
Perfect Video! That's what I was looking for... Big Thanks
alsh123am You're welcome! :)
Cleared it right up for me. Thank you so much!!
Now it makes sense!! Thank you so much
So awesome. Thanks very much for your help. You just helped me ace physiology
Riima1 you're welcome! :)
Thank you AK!!!
you are the best, happy to find you ;)
thank you so much for the video!

Second time watching this.. I wish I could like your videos more than once!
Thanks Thanks Thanks forever ❤️❤️❤️
Great explanation! Thanks much.
Amazing video, it helped me a lot with physiology. Thank you very much :)
lullu927 you're very welcome! :)
You should have an app with all your videos!!
Thanks for this great work👌
Bravo
well explained! thank you so much from the bottom of my heart sir 💜
great explanation, thank you
Thank you for clearing my concept.....
well explained, thumbs up and subscribed.
Thank you !
Wow ! I finally understand!Thank you :)
Thanks Thanks👍🏻
Woow Amazing!!
Tosan Esoko thanks! :)
U welcome :)
great video😍😍😍
Thank you man you are the best there is ! :)
insta-likee!!! 34s into the video i already knew that this guy knew what he was talking about!!
Very well explained. thank you aaaaaalooooot !!
What a lecture!
it is true that they help in expantion but how they help in preventing constricting because if we remove surface tention from water baloon its wall will constrict and baloon will break.
You are awesome. Thank you so mucj
Is it possible for the alveolar to over produce surfactant? Could this happen with reactive type 2?
In your previous videos, I thought you said when we inhale the alveoli decrease its size. Now you're saying that alveoli expand when we inhale? I'm confused...I love your videos!!
Thank you !! 😃
God bless you

when did this happenm
great lecture
dorathy ojimba thanks dorathy
so much better than khan academy for the same video. ALready donated
thank you very much
thank you.........
you are great!
HagayLad thanks!
whats the time
Thank u sooooo much sir
job desrciption thanks
thanks
great
Thanku
what does this meanms
Legend .
This was 80 percent about surface tension and 20 percent regarding surfactant
thank you so much =)
surgfectant not visible internet meaning what is that i have a taelevision
Thank u sir
that is easy niumber up google rated share price etc..accept collpse on support cortex pulmonary..direct....
can we tal;k...
You are God!
But you didn't explained how it prevent collapsing of alveoli? ??
pause 16:00 and read
its a glass of watr of a mitochondria do u still have that book...what happens if the defination is not foubnd..its a piece of paper...
And that is exactly why COVID-19 so dangerous.
calculate the force
yes usb
still don't understand why the alveoli collaps
I mean without surfactant
+Helena Vande Weghe you should start from the basics and work your way up. understanding this concept involves understanding many smaller concepts.
