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 .
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!! 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.... :)
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!
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!
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.

riken maharjan I was struggling with same doubt , thanx to clear it .
I love how he repeats himself to ensure you get the message
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
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 ❤️
The only lecture I have found useful! Thank you!

You are such a talent I have never met in a million years. Wawooo. Thanks so way so much . Clearly understood everthing
Love your lectures! the way you explain everything is wonderful and you make everything make sense. Thank you so much
I've been trying to understand this and you have made it so much clearer. Thank you :)
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!
Erin Blair Thats wonderful to hear Erin :)
Unstoppable. Thank you, great work!
Cleared it right up for me. Thank you so much!!
I understood the whole subject within the first 7 mins! you have a talent of teaching :)
Thanks :)
Thank you very much, I always follow my lessons through your channel. I follow you from Jordan and admire your lessons.
I honestly love you AK
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

Now it makes sense!! Thank you so much
Brilliant!!! Well explained
Your videos are exceptional!
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!
Thank u so much sir for great efforts and explanation.
From India
well explained! thank you so much from the bottom of my heart sir 💜
thank you so much for the video!
Great explanation! Thanks much.
You make what seems hard, easy .. thank you
Malek Ahmaro :-) you're very welcome!
Thank you AK!!!
you reallly explain good , thank you
So much hard work he put to make us understand the difficult topic in a simple way... thank you..God bless 😊
Thank you for clearing my concept.....
So informative are your lectures, thumbs up
Wow ! I finally understand!Thank you :)
Perfect Video! That's what I was looking for... Big Thanks
alsh123am You're welcome! :)
Second time watching this.. I wish I could like your videos more than once!
now i understand what surfactant is . thanks so much
you are the best, happy to find you ;)
Thanks for this great work👌
Bravo
well explained, thumbs up and subscribed.
Thank you man you are the best there is ! :)
great explanation, thank you
Thank you !
Very well explained. thank you aaaaaalooooot !!
Very.....very nice lecture . Now I understand full about surfactant. Thanks sir ...God bless you
Deljinder Singh you're welcome! and thanks :)
Nice teaching as always
You should have an app with all your videos!!
What a lecture!
So awesome. Thanks very much for your help. You just helped me ace physiology
Riima1 you're welcome! :)
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
You are awesome. Thank you so mucj
Thank you !! 😃
Amazing video, it helped me a lot with physiology. Thank you very much :)
lullu927 you're very welcome! :)
thank you.........
God bless you
thank you
great video😍😍😍
thank you very much
insta-likee!!! 34s into the video i already knew that this guy knew what he was talking about!!
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)
Thanks Thanks Thanks forever ❤️❤️❤️
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.
Is it possible for the alveolar to over produce surfactant? Could this happen with reactive type 2?
Legend .
Thank u sooooo much sir
thank you so much =)
great
job desrciption thanks
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 u sir
Woow Amazing!!
Tosan Esoko thanks! :)

you are great!
HagayLad thanks!
great lecture
dorathy ojimba thanks dorathy
Thanku
when did this happenm
so much better than khan academy for the same video. ALready donated
that is easy niumber up google rated share price etc..accept collpse on support cortex pulmonary..direct....
This was 80 percent about surface tension and 20 percent regarding surfactant
whats the time
You are God!
what does this meanms
surgfectant not visible internet meaning what is that i have a taelevision
can we tal;k...
But you didn't explained how it prevent collapsing of alveoli? ??
yes usb
sometimes
calculate the force
in italy
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...
