To be honest, I have one of the most renowned bio teachers in my city, like he's known for teaching really well apparently. However, your video cleared the concept for me in literally 14 minutes MUCHHHHHHHHHHHHH better than he did over the course of two weeks!!!!!!!!!!! Thank you so much, Sal. 😊
always so grateful for videos from khan academy and specifically Sal’s lessons! I always click on the video hoping to hear Sal’s voice and when it’s him, I get so happy lol he explains difficult concepts so easily and effortlessly 😂 best instructor out there, best one I’ve ever gone through! thank you so much Sal!
this is what education is about, free, informative and no bigotry. I do not have to deal with some liberal agenda or some conservative piety, just the knowledge for me to consume. Thanks Kan heres to many more videos. I am using these to help refresh myself to study for the MCAT
This is absolutely fantastic, thank you so much. Truly a lifesaver! Would it be possible to repost the recent kidney videos that were deleted? Thank you :)
I'm so glad that you take the time to explain concepts like this. There's not enough time in my Bio class to explain as in depth as this, so this acts as a supplement for me! thanks!
This amazing channel is free and I can't thank you enough for being here and helping students like me who can't afford even low membership fees. Please don't forget people like me and continue to make FREE contents as you are amazing at explaining things and making the most informative short videos! ✨❤🙏
You pay thousands of dollars for lectures that don't make much sense to you but this guy does it for free in 14 minutes and you completely understand it.
i cant believe how much time you save me from watching these, instead of me having to read through pages and pages of my textbook and still being left confused by the end of it THANKYOU! :)
its those new school slides that make it hard to relateto, when the lecturer actually draws pic & writes words it gives you a better chance to absorb it
Thank you!! Don't stop the "gross over simplifications" They put everything into perspective, these videos are amazing supplements, I have so many haha moments :)
So when glucose is getting back in blood stream then Na must also and also K must be entering and how des K enter the proximal tube or it does not enter
Hey, Khan. I LOVE your Biology videos. I've learned and understood SO MUCH. Could you perhaps do a video or Transcription, since I don't quite get it (with the lagging strand, Okazaki fragments and all that).
If you decide to make more bio videos, could you do some on Botany, and perhaps more on the nervous system, specifically brain structure? Thank you so much for all you've done.
@abodxox Since the [K+] is high on the outside, then it binds to the pump without energy so it changes the shape of the Na+/K+ pump and K+ gets relaesed on the inside just like a carrier protein.... if u dnt still get it then....look up on khans videos on Sodium Potassium pump at 1:38.... ignore the first bit of the video about neurones.... hope this helps
great lecturs, but if you just give a tip how to have access to whol system, for exm: Renal system, Respiratory system. It hard to find the parts. Thank a lot in advence
u explain better than my lecturers. gosh these lecturers shuold really attend a course on how to even speak properly. they have such poor communication skills.
Why can't just every teacher explain it and make it seem as easy as you do? Instead of making their students cry with frustration because they can't give a good and simple explanation such as this?
yep... probably because most of our professors are involved in research and have a concentrated, super in-depth knowledge in these areas. it's their blessing and their curse, methinks :/
thank So much, that's really useful. I love it, I wish that people realise that knowledge is power, and I think you're doing it right. I also saw your video about buy vs rent and I totally agree. Anyway, thank you again. Life is beautiful :)
i wish i found these videos like months ago, my exam in may 6. Thank you for sharing and making science which i hate actually interesting and fun to learn
Thank u so much for the fantastic, informative video but i have a question if u do not mind : does the lumen of loop of henle & distal convolated tubules have cells or only lumen (space)?
wow lol.. i wish I had this when I took Human Phyz lol.. But I didn't have too much trouble with the Kidney though.. I was the heart test that was tough.
Yesterday i was a beginner at Bio class, Today im officially a Doctor..(Y)
7 years later, your videos are still saving lives
indeed
make that 10 years
@@sofiyavyshnya6723 now 11 years, dam time flies by fast.

THANKYOU! :)
You just made crystal clear what my teacher is trying to hammer in my head for the last 3 weeks in about 12 minutes.
Nice job
really dono why this doesnt have a million more view, could help alot of medics out there
Your videos are brilliant. Best on RUclips and getting me through my studies. Thank you
Thank you soooo much! This and the "The Kidney and Nephron" video are pretty much why im going to pass my Bio test tomorrow!
I'm truly grateful for what you do. A lot of stuff I've learnt I owe it to you. Thank you.
Abosultely fab, revising for second year uni human bio' exam and this has saved the day when passive reading kicked in!!! Thank you soooo much ; )
its those new school slides that make it hard to relateto, when the lecturer actually draws pic & writes words it gives you a better chance to absorb it
Thank you!! Don't stop the "gross over simplifications" They put everything into perspective, these videos are amazing supplements, I have so many haha moments :)
Thank you very much for your videos! It makes my medical school life much easier!!
greatly simplified!! that was of great help! thanx!
Thank you :) I finally understand selective reabsorption!!!
i love all of your videos and they have helped me so much in cleaning up the basic concepts taught in dental school. Thank you so much!
Every thing just clicked after watching this. Thank you.
YOU ARE THE BEST, THANK YOU. LOVE THE WAY YOU SIMPLIFY THINGS IT REALLY HELPED ME IN MY STUDIES. KEEP IT UP
At 9:03 , Its 2 sodiums that need to bind to transport 1 glucose. As such, 3 sodiums need to bind to transport one Amino Acid.
I was just joking you are amazing.......you are a life saver
Thank You so much, please keep making more, you are by far the best, by far! You make everything so clear. Please keep it up!
thank you @khan academy i learn so much with these videos, more than lecture. im so so SOOOO thankful
This video just saved me ..Thanx Salman Khan
I had to watch it twice. but I been telling all my other classmate about Khan Academy. Excellent work.
You made our scripted discussion super easy to understand! Thank you so much!!
Fantastic explanation and graphics...thanks for clarifying yet another seemingly obscure situation.
why does everyone make it so hard, except you?! Can you please teach our teachers?!
If it wasn't for ALL your videos I would definitely not be doing as well as I am in A&P. Thanks for "dumbing it down" for me.
So when glucose is getting back in blood stream then Na must also and also K must be entering and how des K enter the proximal tube or it does not enter
Wow... yesterday i was a begginer at school, Today im a Doctor *Thumbs Up*
that was so awesome thanks SO much. wow life saver. wish my prof was like this. helped SO much please continue to make more biology videos!
Love your videos, the visual is just what I needed. Thank you!
Thanks for your videos. I love them. They're easy to understand all of the process.

Thank you! This helps clarify many things!
Thank you very much! Excellent tutorial.
Same idea ! Saaaame Idea !
Really good explanation ! Thank you
Watching it like the third time, Always helpful.
gotta luv yr 11 human bio, thank you for making it make more sense!
you are a life saver..so helpful!!
Thank you! This is very helpful!
amazing as always
Now that was amazing..........9.99999999999/10
You are amazing! Seriously! Thanks you!
Thank you so much for this information!
I completely agree, this is fantastic, THANK YOU SO MUCH for taking the time to produce these. Incredibly helpful, and easy to understand :-)
great lecturs, but if you just give a tip how to have access to whol system, for exm: Renal system, Respiratory system. It hard to find the parts.
Thank a lot in advence
At 11:20 sal said descending loop of henle,maybe it will be ascending loop
u explain better than my lecturers. gosh these lecturers shuold really attend a course on how to even speak properly. they have such poor communication skills.
Why can't just every teacher explain it and make it seem as easy as you do? Instead of making their students cry with frustration because they can't give a good and simple explanation such as this?
I wish I had Khans brain right now..
thank you for these videos. enough said.
you are a Life saver ! Thank you Thank you :)
yep... probably because most of our professors are involved in research and have a concentrated, super in-depth knowledge in these areas. it's their blessing and their curse, methinks :/
good work sal; keep up the things
God this is my savior!
+Lee Romeo LOL Lee, this teacher is excellent. I know how you feel. I also have just discovred this.. (doing a post grad course)
When this video was published, I was 11 and in 7th grade.
thank So much, that's really useful. I love it, I wish that people realise that knowledge is power, and I think you're doing it right. I also saw your video about buy vs rent and I totally agree. Anyway, thank you again. Life is beautiful :)
Thank you! I love your vids.
Great video
Thanks
life saver....CLASS video
lumen = the central cavity of a tubular or other hollow structure in an organism or cell.
i wish i found these videos like months ago, my exam in may 6. Thank you for sharing and making science which i hate actually interesting and fun to learn
Calcium, Potassium, and Sodium are mentioned. How is Phosphate balance affected?
Great video!
Thank you
Thank u so much for the fantastic, informative video
but i have a question if u do not mind : does the lumen of loop of henle & distal convolated tubules have cells or only lumen (space)?
thanks so much !!!!!
thank you!
Fantastic, thanks :)
what would i be without you...
thanks (:
thank you!!! this is very precise and helpful...make more videos :))
thank u so much xD do ya do videos on anatomy for mbbs students ?
Correct (at the moment). The top comments have changed since my previous comment. Maybe I should have quoted those comments to avoid your confusion.
PLEASE SO MORE VIDEOS ON BIO :)
thank yooooouuu
you are amazing!!!!!
wow lol.. i wish I had this when I took Human Phyz lol.. But I didn't have too much trouble with the Kidney though.. I was the heart test that was tough.
It helps me internalize it more when I know more than I need to it seems
How can it be against their concentration Na ions are more in proximal tube so obviously it will go out
I love you :*
HOLY CRAP I JUST GOT IT.
griffith uni represent?
fascinating
YES
love u sal
What bit do you not get?
what about the shorter loop of henle...this model does not work for that
