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
I love how he repeats himself to ensure you get the message

Erin Blair Thats wonderful to hear Erin :)

You are such a talent I have never met in a million years. Wawooo. Thanks so way so much . Clearly understood everthing

riken maharjan I was struggling with same doubt , thanx to clear it .
You are the only one make me understand this surface tension.
Thanks my teacher ❤️
Thank you so much! I have been looking for this explanation for years now. You are awesome with details. Thank you again.
The only lecture I have found useful! Thank you!
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 understood the whole subject within the first 7 mins! you have a talent of teaching :)
Thanks :)
You make what seems hard, easy .. thank you
Malek Ahmaro :-) you're very welcome!
Thank you very much, I always follow my lessons through your channel. I follow you from Jordan and admire your lessons.
Love your lectures! the way you explain everything is wonderful and you make everything make sense. Thank you so much
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

OMG! This totally makes sense! Thank you so much for sharing your knowledge!
Rachel Park You're welcome Rachel!
So much hard work he put to make us understand the difficult topic in a simple way... thank you..God bless 😊
I've been trying to understand this and you have made it so much clearer. Thank you :)
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
time and effort saved !!! norwegian guy thanks u !!!
Thank u so much sir for great efforts and explanation.
From India
I honestly love you AK
So informative are your lectures, thumbs up
Your videos are exceptional!
Unstoppable. Thank you, great work!
Brilliant!!! Well explained
you reallly explain good , thank you
Second time watching this.. I wish I could like your videos more than once!
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)
So awesome. Thanks very much for your help. You just helped me ace physiology
Riima1 you're welcome! :)
well explained! thank you so much from the bottom of my heart sir 💜
Cleared it right up for me. Thank you so much!!
Perfect Video! That's what I was looking for... Big Thanks
alsh123am You're welcome! :)
now i understand what surfactant is . thanks so 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!!
Nice teaching as always
Thanks for this great work👌
Bravo
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 the best, happy to find you ;)
Now it makes sense!! Thank you so much
Thank you for clearing my concept.....
Great explanation! Thanks much.
well explained, thumbs up and subscribed.
Is it possible for the alveolar to over produce surfactant? Could this happen with reactive type 2?
Thanks Thanks Thanks forever ❤️❤️❤️
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!!
great explanation, thank you
when did this happenm
Very well explained. thank you aaaaaalooooot !!

Thank you man you are the best there is ! :)
whats the time
Wow ! I finally understand!Thank you :)
great video😍😍😍
insta-likee!!! 34s into the video i already knew that this guy knew what he was talking about!!
what does this meanms
Thank you AK!!!
thank you so much for the video!
surgfectant not visible internet meaning what is that i have a taelevision
You are awesome. Thank you so mucj
What a lecture!
Thanks Thanks👍🏻
Woow Amazing!!
Tosan Esoko thanks! :)
U welcome :)
great lecture
dorathy ojimba thanks dorathy
But you didn't explained how it prevent collapsing of alveoli? ??
God bless you
Thank you !! 😃
can we tal;k...
Thank you !
This was 80 percent about surface tension and 20 percent regarding surfactant
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...
thank you.........
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....
you are great!
HagayLad thanks!
thank you very much
Thank u sooooo much sir
thank you
Legend .
thanks
Thanku
great
pause 16:00 and read
And that is exactly why COVID-19 so dangerous.
thank you so much =)
Thank u sir
job desrciption thanks
You are God!
calculate the force
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.
yes usb
add subtitles please
