Ninja Nerds!
In this lecture Professor Zach Murphy will be teaching you about Surface Tension and Surfactant in Alveoli. We will be outlining the significance of the air-water interaction in the alveoli of the lungs. We talk about how this air-water interaction increases the tension within the alveolar walls, increasing the collapsing pressure of the alveoli. We also discuss Laplace's law and show a diagram of the histology of the alveoli. In addition, we talk about surfactant and its function to naturally act to decrease surface tension. In the presence of a pathology, when surface tension is high and surfactant production is low, this can lead to infant respiratory distress syndrome, which is described in this lecture. We hope you enjoy this lecture and be sure to support us below!

Salute to all the doctors who passed without these videos
😂😂😂😂
Their concepts would be horrible
Right! Bc there is no way I EVER could 😂

😅😅😅. I salute your appreciation to this Superhero. I really found cordially wishes for him
why can't our professors teach us that way????? I can't believe I pay for my college to get back home and watch a great person life you teaching for free.
life Is unfair, but thank you thank you from the bottom of my heart!!!!!!
True 😓 It's good this chanel exists ❤ I'm so grateful
I do agree!
والله كلامك صح
I definitely also agree!!!
Great to hav u ;; u r best in world I think sir
Hate to say it but some videos are WAY better than university lectures! Very well explained. Keep up the good work. :)
Glad we could help!
Trueee , University lectures were just time waste for me .
exactly
Bro, not some ALLL the lectures are better than University ones ,in my case😂
This is completely TRUE.
You are saving my butt. Thank God you paid attention in school. 😁
It isn't your "butt" he was focusing on in this vid. That is, unless
you actually breathe through your butt. ROTFL!
Props!!! These are great videos. Confession: I put you on double time for all you lectures and I really like that you use the white board to both draw and write the concepts you talk about. I mean, obviously, if I'm on CZcams watching lectures, then I'm a visual learner by nature and most likely have a shorter than average attention span. On double time, your lectures are a little over 20 min soit perfect for me. I don't find myself getting distracted waiting for you get to your next point (or to finish drawing 25 water molecules 😁 ) So thanks for providing content for learners like me and keep up the great work. These videos are a fantastic way to refresh and review these essential building block topics of Anatomy and Physiology.
Bro, I like the way he teaches weather he takes 20 or 40 min if u don't have time then increase the speed of lectures . 😑😤🤨🤨😐
@@happybhimani2435 that is exactly what he said hes doing
subhan allah I was amazed by the fact of the first baby cry . The way our body works really surprises me every lecture 😭😭❤️
Subhhan allah😂😂 ماتترجم
So I'm in med school and they loooooooooooooooooove you. The ones who get honors live by your vids
+1 I love this man (NO HOMO BRO) XD
you're litterally saving my first year med school exam and I'm so grateful for it ! i'm watching you from France and you explain waaay better than my actual teachers ! keep on going
I would really express my sincerely feelings toward your great helful video , I haven't seen ever such a great video like that , please keep on the good useful work . Thank you so much.
+Khalid Ali awesome I'm so happy we were able to help!
Incredibly well explained, it's good to see someone so passionate and naturally engaging in what they're teaching. May you never be bored a day in your life sir, well done!
hey man i learning about fetal lung maturity and i was so confused because the textbooks would toss around terms without explaining the mechanism of surfactant, only that it "decreased inner alveolar surface tension".
ive gone through my previous textbooks and other websites but your video really shone the spotlight on every single aspect needed to fully understand surfactant and inner alveolar surface tension.
massive respect and thanks, keep up the great work.
I have never seen such a good teacher in my life! I highly appreciate the hard work put, by the whole team, into making these videos. I literally recommend this channel to every student I see. Keep up the amazing work Ninja Nerd.
Satisfaction is when the complex topic is cleared as water. Thanks for that providing that amazing feeling
East or west u r best lecturer in whole medical world🙂🙏
"must've been some dude named Kohn who figured that out" 😂😂
Incredibly grateful for your work. Would appreciate more lectures on pathophysiology! Thank you for doing what you do!
#Respect
I wish , I wish that our college lecturers had at least 10% enthusiasm as you have sir.
Thank you for this amazing explaination
I was so confused about how the surface tension works and how the surfactant decreases the surface tension. But this video explained all the concepts so perfectly that now I understood it. Thank you so much guys.
I've never heard surfactant explained this way, and this made it finally click. Thank you so much for all that you do!
You are one of the best teachers I have ever seen! No exaggeration. Your videos are helping me understand the material we are learning in paramedic school. Please keep it up!
I am working on a presentation for my physiology club in residency and I spent HOURS trying to understand the whole surface tension surfactant interaction, read 2 different physio book chapters, watched like 3 CZcams videos but NO ONE explained it better than you! I am incredibly happy I stumbled into your channel :)
This is the best channel on youtube for anything anatomy/physiology or medicine based BY FAR. Zach you are the man
I am taking Physiology and was lost with the lecture videos from my prof; I did a search and I see you pop up (your videos are always very helpful). I've never seen anyone teach with such passion, you are gifted and were clearly born to teach! Physiology is amazing to think how everything works so perfectly together. Thank you!!
i wish i had someone like this as a teacher. our teachers don't explain half as good as this guy. thank you.
Your lectures are sumptuously explained, can't get better than this.... Salute to your hard work
I just love the way he teaches! I feel like there isn't any one better than him in teaching these contents!!! I'm a med school student in Brazil - just started- and this is helping me a lot!!!
Incredible explanation. Thank you! The mechanism of surface tension at the beginning followed the mechanism of surfactant at the end is pure gold.
I'm a materials science major taking a class about materials for medical devices and surface interactions. My professor recommended this video. Thanks for taking the extra time to make the vocabulary understandable to someone who has only taken two freshman biology classes.
That feeling you get when you listen for 20-30 minutes and it all comes together in the end! Love it!! New subscirber
I am watching you from the UK and think you are an amazing teacher. So wish I had you teaching me when I was back in school. I can see the passion you have for teaching. Keep up the fabulous work.
These videos are great! I am in my first year of medical school, and these videos help to fill the gaps in my understanding. It is amazing how these videos are easy to understand, yet don't do so by leaving out information.
THANK YOU!
This material is fantastic. Not only is it accurate and in-depth, but presented in a way that's easily retained. This page deserves more recognition. I wish I came across it sooner. Thanks and please keep it coming !
+Garrett Hovagimian We plan to keep them coming and would really appreciate the support by sharing our channel!! We love creating content for this channel and every share and like really helps! Thank you for all your kind words Garrett!
I truly love you! your whole teaching method is amazing and I love how you recap as well. I have so many drawings that are going straight into my binder and I am never letting them go!
I am grateful to have met one of the most exhaustive professor who helps me understand the human body!
You are just an amazing young passionate scientist that deserved my great respect fella! 🙏💟💪Big thanks from egypt for that great effort ! Keep going.
Excellent. You were born to teach. Teaching is an art and not everybody is able to do it. I am sure that you are giving lessons to the professors themselves . Go ahead .
Seriously!!!! You are a fantastic teacher. Thank you!!!!!! Ninja is out there saving medical school grades.
You are my go to in nursing school. You break your videos in a way that the hardest concept is made so much easier to understand. I have a achieved so much in nursing because of your videos. Just want to thank you for all you do!!
always so happy when i see you have a video on the subject i have to learn
This made so much sense! Your videos are really helping me get through the Respiratory Therapy program. Thank you!
thank you so much...im going to cry because this makes actual sense now :')
@Ninja Nerd Science, this is BY FAR the best video on the topic. I am studying for my MCAT and this helped a lot, more than my $500 textbooks. Love the way you teach. It's simple and encouraging. Keep up the good work.
My god, thank you for all of your videos and the way you explain everything in detail. I study, read, listen to my instructors, and I have an idea of what I'm reading/hearing, but you make it clear as day lol. Thank you!
This guy is awesome! Looking up surfactant online was pretty cut and dry until I saw this. It was very helpful.
You're absolutely incredible at explaining, any university would be lucky to have you as a professor.
You are amazing dude! This is the most insightful medical education film I’ve ever seen.
Can't express with words how amazing these lectures are!
This is one of the best videos I have watched on this space .
Thank You so Much for the vivid explanations❤️
Thank you very much !! this really helps me to understand and what I appreciate most about you is that I feel that you love what you're doing !!!
Such a genius! I am fasting with no sleep but still focused and attracted and paying attention and that’s just because of your marvelous explanation. God bless you
I keep thinking: if there were a lot of hard working lecturers like you around the globe would be so great. You are of great help. I definitely have a folder of almost all your video series and I would keep liking your videos and and downloading. I don't even know how to thank you. But may God bless you and Crew for work well done. if i were to rate your videos it would be the world's best lecture videos ever with valuable, updated and reliable knowledge.😍
I don't normally comment on videos, but when I do, that means I am greatly impressed. Thank you dear Ninja! You made such excellent explanation.
U are too good at what u you do. I just re realize this video has been here for 5yrs waiting for me, thank u so much ❤
People like you make the world a better place! thanks for the knowledge
*THIS VIDEO IS A LIFESAVER I COULDN'T MAKE SENSE OF THE CONCEPT FROM READING THE BOOK, GREAT JOB*
Ninja nerd is my teacher of physiology and thank you so much for your helping me. Your lectures are more clear than my university lectures, keep going.
Thank youuu so much !!!! you're not just an EXCELLENT teacher, You're a HERO!!!!!
I was turned off from the 46 min of the video but it's by far the best explination of this phenomenon. Thanks!
wow this whole 40-min vid was totally worth it!! the way you explain things is really amazing. this is the first video i've ever watched from your channel, i gotta see the other ones too! new subscriber here ^_^ thank you for this wonderful content, sir.
I have never been so enlighten about this til now. I am so glad i found you! Hahaha thanks a lot, sir!
Hey I am really thankful to you for your these lectures!! Your videos are simply amazing nd way much much much much better than any other lectures we had in medical school !! You are doing a great job plus the way you teach with so deep understanding of subject nd topic is commendable !! I've seen many of your lectures nd trust me it has helped me like hell !!
P.S. The ratio of understanding the topic from your videos to from books nd by self study is 60:40 !
I really appreciate !
Hi! I'm a medical student from Indonesia, your videos have been very helpful throughout my pre-clinical days. Keep making stuff like these and inspiring students to NOT GIVE UP, even the hardest subjects can be explained :D You rock, Ninja!
This video was very helpful. Thank you so much for making these subjects easier in a professional yet funny way!!
great presentation ninja nerd. You blew my mind when you explained how the hydrophobic heads balance out the forces at the top layer of water. Thanks!
Thank you so much for this informative video, It was a real struggle to find a decent explanation of surfactant and its role in the respiratory system online!
These videos doesn't get the credit they deserve. Thank you for all the effort you put into them :)
This is such a great video! You have a real passion for physiology! Please keep making this content!
pathology resident from germany here who needs to revise some basic physiology :D just wanted to let you know your videos are helping all kind of people, you are a great teacher
You're saving my butt this semester! Really appreciate your videos. You rock!
You are the first outside of pulmonolgy and Respiratory to give a gold star evaluation. There is hope for better respiratory care.
This video has really helped! You make it addictive to learn which not many people can do. 👌🏼
Bro.... I had such a hard time studying out of the textbook... You made it so much easier, even compared to other videos. Very intricate (which is good). Keep it up!
absolutely brilliant ...u explained clearly in a single video wat so much of study cannot do
thank u so much!
Thank you for this this video. This can really help me with my upcoming final exams. ☺️
Explanation 10/10. Thank you so much☺️🤩 He puts all effort on theme and draws amazing!
Thank you for making these videos, they are excellent and you teach really well! Enjoyed watching it as always!
THIS IS FANTASTIC! thank you so much! Please do not stop making videos!!!!
This was great! thank you :) We need professors like you!
it was the best learning experience i 've ever had .cant believe it was all free. thank you so so much
i have a test in 5 days about this stuff and reading the text only confuses me, but watching your videos after the read puts it all together thank you for taking the time to make these videos i hope you get to achieve all your goals in life!!
this guy is the best, and I mean the best ever in explaining stuff. THANKS MAN
Trying to put my whole med school class on to you because you’re a G. I literally modeled my teaching style in our mini-presentations off of the way you simplify, summarize, and use the board.
Love your way of teaching, Really helps my understanding of respiration. Thank you!
+Mikkel Christensen So glad it helped! You are very welcome!
I am a high school student in Korea. I watched this video for the chemistry performance evaluation at school, and it made sense to focus on this video and watch it once rather than reading various explanations in Korean! It helped me a lot, and thank you for making this informative video :)
You are phenomenal! I enjoyed watching your video. You explained this topic very well. I am now ready to work on my presentation. Keep it up. You did a fantastic job! God bless.
Its more effective than my professor's lecture.. Making my quarantine study time more productive...Thanks alot :)
another excellent video, breaking things down better than any other resource. thanks.
This is amazing! I'm doing a project on the importance of pulmonary surfactant and this really helped me understand the whole process tysm!!!
Your explanations are so smooth that every concept at the end is bound to get correlated with the other, like we used to prove LHS=RHS in those High School Numerical problems!!!!
The best doctor explaining physiology in the world❤
sir no words but just to say you are amazing and best teacher on youtube I have ever seen
One of the best videos I've seen. Thank you so much.
One of the best lecture videos I've ever watched
This was so helpful!! I was really struggling with this topic. Thank you!!
This is so helpful! Your videos are great for MCAT studying. Thanks!
words can not describe how your videos are useful and helpful for us as Medical Students keep up the good work thank you so much for this great Job love you and your team ^^
Thanks a lot. Your videos are wonderful. Clears the concept. Very helpful. I first see your videos and then consult the text books. Helps to understand them better.
needed to appreciate it. Thank you Doctor, chemist and Sir.
Just wow!!! Awesome lecture. Thank you for sharing your knowledge and passion.
I really felt like a damsel in distress whenever things came to this concept....you truly saved me. Now it seems a piece of cake
Great teach! Keep going !
