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 :)

[@jseanbrooks1]

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.

[@Ess1g4c1z]

More like Ideal Gas Law but the same thing. :)

[@Sheba_316]

Boyle's law explained simply... Thank you

[@eshalima2714]

Thank you very much!

[@sashaandersen2451]

Thaaaank you, sir:-D!

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.

[@mursalinhasanchowdhuryalfi817]

exactly. but nice video. very educative.

[@JesseStevenPollom]

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.

[@elviragill8248]

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!!!!

I love this analogy! Thanks for being such a great teacher.

[@nicholekeller2737]

Him turning the drawing into a lung thinking we don't already know what it is lmao! Thanks for the video!

[@HERBavoree]

10:45 moment i began to realize my mind was about to be FUCKED

[@axisgraf]

you sir, Dr. Desai--are an awesome teacher! this is by far the best explanation of the process.

[@mstearused]

this may have just possibly saved me! exam tomorrow!

You bamboozled me there at the end. Love it!

[@zhangmartin5872]

What a great class with the febulous hand drawing and very easy understanding explanation. A worker from China. Thank KhanAcademy. Thank the teacher.

[@LizDavies14]

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!

[@rajkalalamba1274]

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.

[@khaledebrahim90]

i really appreciate your efforts 😍 thank you soooooo much.. your student, from egypt😊

[@JesseStevenPollom]

Absolutely incredible video. It's oversimplified, but necessary to simplify in order to get the main concepts. Great great video.

[@kyotalimyeesther4968]

It's the best thanks

[@viaan6516]

U are my favorite speaker 😶

fucking legends who helps with school me long lives kingss

[@babyhelloO]

Holy moly, I actually understand! Thank you so much!

[@salinanair68]

helped me a lot before my bio test. thank you

[@zamus2004]

You talk exacly like sal ! :D love it

[@elviragill8248]

😊The person is indeed Sal Khan

[@childofagape]

Elvira Gill no it was not Sal, but Rishi that taught in this one.

[@primalairomt6542]

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.

[@jared8411]

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?

[@languageandmana9255]

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❤🩺

[@sidrafashions5839]

I loved the way you changed you drawing at the end but the concept remains the same. Best video to understand the concept ❤️👍🏻

[@mauriciaislas7415]

WOW, Thank You Khan Academy for helping me understand this material a lot more clearly!! You ROCK!!!!
