You described Boyle's Law in this lecture without recognizing it :) (For all of you to know!!!: P1V1=P2V2) Pressure and volume are inversely proportional. That is the main takeaway message :)
I've been struggling with the gas laws and during the video I was thinking hmmm, sounds like Boyle's Law but I wasn't sure if I was getting the gas law names mixed up again.
More like Ideal Gas Law but the same thing. :)
Never will i cease in shouting out my thankyous😊💜 KhanAcademy has been my own personal tutor in soo many ways!!! Thankyou for posting such helpful material for Respiratory Therapy students! I appreciate every single video....I really do! Thankyou for making such a complex physiological action simplified and explained in much detail...THANKYOU! Blessings to your team, your family and all that you do!!!!
Elvira Gill My name is Rishi Desai and I work at Khan Academy. If you're willing to share a bit about your experience as an RT student, please send us your email address so we can reach out to you. Thanks in advance!
khanacademymedicine Rishi Desai you are one of the best teacher. Thank you!
☝️
This is one of the greatest videos I have ever watched.
Him turning the drawing into a lung thinking we don't already know what it is lmao! Thanks for the video!
Thank you so much for your videos. I am a physiotherapy student currently studying Cardio-Respiratory and this has been of so much help to me. Your videos are always broken down into easy to digest segments. I would recommend them fully!
Thanks again Khan Academy! From A-Levels to Masters!
I thank God that I came across this channel at this time. I feel lucky and good. Thanks for teaching such a hard subject (biology) in a better way. You are doing a great job.
I love this analogy! Thanks for being such a great teacher.
you are helping me so much I am a nursing student
You bamboozled me there at the end. Love it!
thank u so much u made me understand every thing finally u have the best way allah bless u
What a great class with the febulous hand drawing and very easy understanding explanation. A worker from China. Thank KhanAcademy. Thank the teacher.
you sir, Dr. Desai--are an awesome teacher! this is by far the best explanation of the process.
Absolutely incredible video. It's oversimplified, but necessary to simplify in order to get the main concepts. Great great video.
Explained it so perfectly!
It's the best thanks
This guy teaches great! Has a great voice for teaching! Wow! I love you medical videos especially like heart and diseases! I wish your videos was more detailed and i could gain more information like a doctor has! I can watch your videos for hours❤🩺
this may have just possibly saved me! exam tomorrow!
Bitch
Lol
U are my favorite speaker 😶
Dude.. You rock! Awesome presentation! Making physiology more digestable!
WOW, Thank You Khan Academy for helping me understand this material a lot more clearly!! You ROCK!!!!
Good explanation and good drawing and be safe and good luck
i really appreciate your efforts 😍
thank you soooooo much..
your student, from egypt😊
Awe. Thank thank you a million times. I did not understand this until now. Totally make sense.
helped me a lot before my bio test. thank you
Holy moly, I actually understand! Thank you so much!
I loved the way you changed you drawing at the end but the concept remains the same. Best video to understand the concept ❤️👍🏻
Perfect except for the mouth part, the organ of breathing is the nose. The nose is pretty complex and alters the speed of the air going in or out. The mouth is the escape hatch.
i love this explanation. it explains negative pressure so well.
So nice of you to do these videos. Very helpful.
Boyle's law explained simply... Thank you
You talk exacly like sal ! :D love it
😊The person is indeed Sal Khan
Elvira Gill no it was not Sal, but Rishi that taught in this one.
Thank you so much. All your videoa are marvelous. ?

Wow
Absolutely wonderful! Thank you!
Thank you so much! You get me through my exams and stress :D
Love all ur videos
Such a creative way to teach! Awesome, love it!
how did you make breathing so interesting?
Excellent! Such a great explanation. I use your videos to reinforce material learned in lectures for A&P. Always helpful. Thanks! :)
Would I be correct in saying inhaling is creating a positive system, and that when I expel I am moving from a positive air system toward a negative? or do I have it backwards?
10:45 moment i began to realize my mind was about to be FUCKED
this was really helpful...thank you :)
Super
I LOVE YOU KHAN ACADEMY

Do you have dental braces? It sounds like. Thank you for your videos!
So... the diaphragm does the pulling?
Correct.
fucking legends who helps with school me long lives kingss
lol your jar! :D
WOW! You took 13 minutes to tell us PV=C.
The difference between pleural and aveolor pressure should be mentioned first. It makes the whole topic quite confusing if someone doesn't get it. This video makes it look like that the lung is actually used for the breathing and not the alveoli. The lung has always a negative pressure, the aveoli don't.
exactly. but nice video. very educative.
Ya so for those curious about this, you at least gotta think about 2 pressures.
1) So the pleura (lining of the lung) has a certain pressure, called the Intrapleural Pressure ("intra"= within, so the P within the pleura).
2) Then think of the main pressure inside the lungs to be the Alveolar Pressure (the P inside the alveoli, little grape lookin things).
-And the difference between those 2 (or the "pressure gradient") is actually the driving force of air flow! And this pressure difference is called the "Transpulmonary Pressure."
And even this is a simplification so obviously the video is a simplification, but I think it's still really really good. It is very often necessary and helpful to learn oversimplified basic concepts before adding the more complex and correct things.
