Secondary Active Transport in the Nephron

[TheFabMaia]

Thank you :) I finally understand selective reabsorption!!!

[yukikohohoho]

thank yooooouuu

[farhadfan]

This video just saved me ..Thanx Salman Khan

[Kaz302755]

really dono why this doesnt have a million more view, could help alot of medics out there

[hiamynameisholz]

can you do one on the loop of henle?? :(

[TECHNOTRONIXXX]

my book says secondary active transport goes against the concentration gradient ? this video just explained the sodium going from high to low to replace the lost ones from the primary transport ? so my question does secondary transport go from high to low or low to high ? thanks

[TheBobsmithers]

does anyone know where secondary active transport gets its energy to move glucose and sodium into the cell? Since this is secondary 'active transport' and not faciliated transport, where does the energy come from to bring glucose and sodium across?

[ma88yc]

thank you!!! this is very precise and helpful...make more videos :))

[MarthaPB17]

you are amazing please keep making videos they help me so much!

[bicearoni]

Love your videos, the visual is just what I needed. Thank you!

[bicearoni]

Love your videos, the visual is just what I needed. Thank you!

[Famousx81]

this video helped clarify the structure n function of kidney. the terminology also helped. thanks!

[runawayfastasucan]

Wow... This just helped me ace my MCAT!!!

[raventraine]

you are a life saver..so helpful!!

[theTRUE1414]

you may have hurd this from every one else , but thanks alot.. it made so much more sence now :D ... im suprised how alot of the stuff people learn in the us , links to what we learn in a level in the uk

[reasonrules2011]

its a good lecture with a mistake, a constructive criticism only at 11:19 sir khan says "DESCENDING LOOP of henle" where the chlorine and potassium ion or sodium ion where symporters sodium potassium chlorine co transporter occur "WRONG" its the "ASCENDING LOOP OF HENLE", students might answer a question like "wheres the sodium potassium chlorine co transporter occur, they might answer "DESCENDING LOOP OF HENLE" 1 point mistake might fail them from exam.

[BestWayWeSurvive]

You are a god. I can now finish my freakin bio homework.

[BlackGypoMagic]

Dude, Marry me. No homo.

[Unclenib]

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 ; )

[MyBohemianHipster]

Thank you so much, thanks to you I won't fail my bio test ! :)

Keep it up !

[Underxman]

Thanks for this good video, the explanation is worth gold.

[bajanqt123]

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

[gangsta1kidd]

Yesterday i was a beginner at Bio class, Today im officially a Doctor..(Y)

[gangsta1kidd]

Wow... yesterday i was a begginer at school, Today im a Doctor *Thumbs Up*

[Regenbogenbruecke]

wow, your videos are really great, it's the first time I really understand this :-)

[crs1314]

AHH!!! i wish i wouldve discovered these a bit sooner in the semester!! my last test before finals is tomarrow and these have vastly improved my understanding of the material, Thanks so much!

[smschulte17]

Thanks after reading I didn't understand this fully! Seeing it makes it so much easier!

[Colussi90]

Thankyou- you're the best. The colours and drawings make it much more interesting and stimulating and your enthusiasm helps make it exciting. Keep it up students everywhere need this and will love this!

[princessmaree79]

I learned much more from your video than I have learned by reading my text.Thank you!!!!!

[princessmaree79]

I learned much more from your video than I have learned by reading my text.Thank you!!!!!

[Sheesh265]

WOW..what a gold mine!  Thank you!

Thank you very much! Excellent tutorial.

[JMcAlpin4545]

Nursing school here. Now I understand what they have been pounding in my brain. Wow this sure was easier to understand.

[YAMBS5]

YOU ARE THE BEST, THANK YOU. LOVE THE WAY YOU SIMPLIFY THINGS IT REALLY HELPED ME IN MY STUDIES. KEEP IT UP

[Allisonebruce]

I love this man! I think i actually understand how reabsorption works in the kidney. Please keep these going!

[saralikeskiwi]

how much would it take for my medical school to recruit you to teach us physiology?

[abodxox]

at 5:25...the Na+ went out,ok...but why is K+ going in??? please answer  : '(

[formula1nh]

@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

[abodxox]

@formula1nh oh..ok, thanks that realy helped ^^

[spideryan04]

I have been reading this for days now and have had so much trouble trying to understand it...you have made things so much more simple. Thanks for some brilliant videos...I wish you would come and lecture at my university!

[fnc5404]

really great! thanks for helping me pass my AP2 class!!!!

[buenome]

ok im kinda confused ...what tubule is that and i though all the ions go out

[buenome]

@buenome lol no worries ..mr.kahn answered it after :)

[mmcce10]

fantastic! you are so clear, and you always seem to realize the true aim of what you are teaching! thank you for this clean concise video, and all of your other videos!

[xgoldensunshinex]

You deserve a noble prize!!!

[persephone329]

I had to do a presentation about ESRD for A&P and I just couldn't understand how the nephron worked until my project partner found your videos. VERY HELPFUL!!!!

thank you!!!

[TirathM3]

Changing the world 1 video at a time :)

good stuff

[HorrorDe]

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!

[fs32464]

[g0eschen]

i love you!

[Robeytussin44]

you are the man, keep it up, your changing the world

[Sameer3292]

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. 

[SALW90]

I've just spent three hours watching ur biology videos for my final A2 exam tomorrow :) sooo helpful!

Just makes everything so much more understandable!!

Thanks for all ur help :)

[BestLuJe]

<3 <3

I'm SPEECHLESS !!

thanks a lot !!

ummm can i ask ,, what's the name of the program ur using ??

[BrittneyMPoon]

thanks so much !!!!!

[apoc601]

Thank you! I love your vids.

[AjHignell]

I am also in school and this video is top notch and very precise. Instead of listening to my own recording of this lecture, I instead have this on repeat! Wonderful job khan!

[g3rmb0y]

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.

[styleclash1]

I'm in medical school and this is still better than the lecture I got on this in class, awesome!

[mrthuvi1]

@styleclash1 i'm thinking the same thing!

[Yatizzzle]

@styleclash1

Hahaha...scary

[Nick153452]

@styleclash1 I wish I were in Medical School :-)

[bradleywalters1]

@styleclash1

Agreed. I am also a medical student, and the Nephrologist who lectured us made it so complex it was impossible to understand...KA rocks!

[Arianaslover]

Good job man.. Thanks

[sgtOOX]

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

[fabs1289]

life saver....CLASS video

[Baby2217]

You have no idea how easier you have made my life! I saw your other videos and I wonder..how are you able to understand and remember so many difficult concepts? You're a true genius! Thanks for posting these videos. Keep them coming!

[Fieldsl1]

sir, i didnt think a one single person can be too smart, you are a gift sir

[566karim]

great stuff Thx Sal

do you have a sense about what the countercurrent multiplier of the nephron is.

[MrKicks2010]

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.
