"A"fferent = "A"rrive
"E"fferent = "E"xit
A good way to differentiate between the two.
I just think of it alphabetically
Afferent - Approach, Efferent - Exit
Joella Frozen thank you!🥰
Thank you
thank you so much
It's nice to watch some of these as "study breaks" believe it or not!
Hey bro your comment is 7 year old that means you will be doing job nowadays

@@SolicticeCat as a teacher lmao
Screw my instructor man, u r the best. 4 hrs of lecture didn't make sense as much as this 18 mins did.
actually, 9 min if you put on 2.0
Lol he is here to save you when you take an online class in the middle of a pandemic and the professor doesn't actually lecture; just uploads a PowerPoint full of sentence clauses
@@casa1116 literally spot on... my instructor rambled on unintelligibly for 3 hours on this topic and I learned more from this clear video
Me seeing people's comments from 8 years ago
Like ya'll prolly got your degrees and diplomas huh😢❤
this is my favorite math teacher.
I’m in grade 10 studying for my externals (:
@@argx24 You'll do great 😌🤘
Cassi Jhingoree tysm 🥰 but unfortunately they were canceled
^^^^^ Facts
People don’t realize how much money sal could make off Kahn academy if he mad it pay but he keeps it free because he values the education of people more, real respect
cough cough *byjus* cough cough
Wow. My AP2 teacher did a 2 hour lecture on this ... but you did it in 20 minutes, and i understood everybit of it. You need to be my teacher. You are really a lifesaver , thank you soo much for your videos. It is so good to see people like you helping others , without anything expected in return. god bless.
Damns even ur comment is older than me.
lmao@@climate069
Such a complicated system to understand from only reading but after watching this video everything seems so simple, brilliant!
no one asked you to do this youtube chanel. you have a clean passion mr sal. keep it up inshalah u get everything u dreamnt of
IA
I cannot thank you enough, from pre-algebra to biostatistics, from meiosis to cardiac phases. You have been there every step of the way and changed my life. thank you Sal!!!!
I am taking an anatomy & physiology class and am currently studying the urinary system. This video was very helpful and informative, as well as being easy to understand. Thank you.
omg thanks for this video my instructor sucks! she compares everything to food or her family
+blacmumba lol wat
*Learn How To Lower Creatinine Levels, Improve Kidney Function, and Safeguard Your Kidneys From Further Damage An All Natural Step-by-Step Program, Proven To Start Healing Your Kidneys Today*!" -> kidneydiseaseremedies.blogspot.fr
that is a huge problem
blacmumba sounds mysteriously reminiscent of my old Bio teacher.
SAME. My organic chem professor compared benzene to a hamburger, like tf does that even mean
Omg!!!! Truly amazzzzzing....I've nvr seen any one teaching better than him...thnx!!!
I am in nursing school. It is so NICE to get back to basics sometimes to just review to enhance my nursing practice. THANK YOU SO MUCH for taking the time to make these videos. THANK YOU !!!!
+kathryn wolanyk
I agree!
Second year of nursing and it's good stuff for touching base with all first year teaching.
Same here! Renal diseases are so much easier after this brush-up
i DONT THINK you'll ever see this message but THANK YOU SO MUCH I CANT BELIEVE I UNDERSTAND THE FUNCTION OF THE NEPHRON :)!!!!!!
Hmm. My English teacher told me that nephrons were the plural form of nephew.
hahahahaha
Omygosh he's don't believe everything you hear
This is great, makes so much more sense now that you explained it! Thank you!!
Wow!! I was sat in the library for 2 hours trying to figure out why water ans salts are leaving the tubules and entering again, now it all makes sense!!! THANK YOU!!!!
That was extremely helpful! I truly appreciate your free videos. I have been watching your videos since high school and now you are helping me with the MCAT :)
I love you sir. Seriously. Like I wouldn't have passed hs or college courses if it wasn't for you. Thankyou.
Great video, I've learnt a lot just watching this.
how could u ever dislike this video...? I mean, just, nonsensical. thank you kind sir for your greatness for all us struggling biology students. I salute you.
awesome explanation!!!
The fact that you take the time to do these illustrations is greatly appreciated. My A&P professor is awesome, but to get a different perspective helps alot, love the garbage chute analogy. I thought of it as the show Hoarders, where the family throws out junk (ascending part of loop of henle) and the hoarder picks thru reabsorbs the junk at the in the descending end as the garbage men are getting ready to load it. The collecting duct is the garbage truck. Thanks again, you rock !!!
You know, whenever I go to other channels for information about medicine ( I'm a medical student) I got confused! Even good and informative channels out there are not able to explain things the way you do! Your amazing! Simple but at the same time complex and detailed and informative! And also I have to say that I didn't understand anything by reading the textbook but now that I'm watching your playlist on the topic of unrinary system, I'm understanding everything easily and in detail!!
Thank you for beingg here and sharing your content free as many students like me are not able to pay for even low amounts of membership fees. ❤🙏
I don't have enough words to thank you. You're a wonderful teacher, and all I can say is that I owe it to you that I've come to love biology this much :D
I'm sitting here wondering why I'm paying tuition to my school when the majority of my learning is from Khan Academy?
Yeah, me too.
Thank you for a very descriptive video! not many " teachers" take their time explaining such detailed systems.
I was stuck on this particular topic ! THANK YOU SO MUCH, you've helped me a lot
Thankyou for this very useful video! You did make others love biology more! :)
*has AP Biology Physiology test on Tuesday*
*Watches Khan Academy video because book
+LAURICE MELANIA no thanks i want mine to shut down
Danny Czarnowski LOL I would also prefer mine to shut down XD
True for me 4 years later
@@NPC-se5nx currently in medical school and can confirm that Khan Academy remains a godsend through MCAT and beyond
Omg I have to say this video is terrific and the way the narrator talks about is very meticulous and very easy to understand. I once watch different lectures but still confused at last. But from this I was enlightened quickly! Thank you and your Chinese subtile! Much love from 🇨🇳!!!
Last night I was beating my head against the wall, this morning with Sals voice and explanation, I see the light
You're brilliant!!
thank you so much, i'm a medical student and this has helped me so much!
You must be a doctor or something by now. Right?
Amazing teacher!!! Thanks so much, always helped me throughout my studies!
Your anatomy videos are great! Thanks Sal!
My lecturer went through the kidney,liver and circulatory system in one class.. The last class before our final. Thank you. I have my exam in an hour and this always comes up
Pokemon Maniac Jak are you kidding? those topics in one day, one lecture, just before a final? what demon thought that would be a good idea. what college?
Tyrone Hurst an IT in Ireland. I had a choice between two long questions. One was on all of these topics, the other was on molluscs. I'm still salty over it because it didn't really give me a choice.
"Earn the name urine" lol
Mr. Sal, thank you so much! You always have videos to help with my AP Bio& AP Calc BC! It's wonderful, plus you really make studying so much more exciting.
Not only was that helpful for an upcoming exam, but it was absolutely easy to understand and truly cool. You sure know how to explain stuff!
i guess, learning about the kidney requires...
*puts on glasses*
... alot of concentration
*yeaaaaaahhhhh*
woowowowowowoowowowwowowowooooooooooow; no
hi everyone ,if anyone else needs to find out about
what are kidney disease
try HootKidney.xyz ? Ive heard some incredible things about it and my partner got great results with it.
THANK YOU SOOOOOOOOOOOOO MUCH!!!!! I didn't understand anything in kidneys, but this helped SO much!!! Thank you so so much :D I have my ig tmrw and thanks to you I may just pass
I'm writing a biology test today and this video is really helping. Thank you Sal Khan, may God bless you.❤❤❤
This taught me everything I needed to know and didn't understand. Thanks! Look forward to watching your other videos.
I may just pass my biology GCSEs tomorrow
FreeFireGamer ooh I might too
wtff. You learn this for GCse?!!! i learn this at uni 😂😂😂
Seriously I am extremely curious tho always score 98% . also i have tried all the mcat tests as well .
sobster123 Basic level, nothing too serious, only what was on this video.
yeah exactly
Why in the world can't my teacher say it simply like this.
This is amazing! I'm learning for my paramedic exams and this is really helpful!
Thanks so much! I’m started off as a lab tech, and then became a general radiology tech, but forgot all of this, but now due to short bowel syndrome causing renal failure (Crohns disease, intestinal cancer, and 37 surgeries left me with only 4.9% of my entire GI tract), I went into full on renal failure and countless renal calculi, I discovered what little intestine left (I on my 8th ileostomy, including a j pouch and two failed k pouches) can’t absorb enough fluid and nutrients to keep my internal organ alive and healthy. I lost all my notes from collage due to a house fire, so thanks so much for the refresher, now I remember everything (graduated from the university of Toronto way back knowing 1992 with my masters in lab medicine and in 1996 with my masters in medical radiological medicine). Finally got hold of the lab work for the past 2 years, with my creatinine at 150 at its lowest, and no one told me, so I went into renal failure 3 weeks ago with my level at 271! If it weren’t for my stones, I’d still be oblivious to it, being totally asymptomatic! (Having 37 GI surgeries, you tent to ignore little problems that should really be lid attention to). Can’t believe I’d forgotten everything you just showed, I’m in your debt my friend, now I have the tools necessary to get back to normal renal function…stated myself in 1 L if saline infusions via a single lumen PICC line every other day….I’m down to 130, almost normal, and fell 100% better, especially now that I can remember all the details thanks to your video! All the best, cheers!
Hello stranger, i am glad to hear you are doing better! I hope you will be doing even better in the future and life a good and fulfilling life.
@@Amin2k thanks so much!😁
"It doesn't happen by magic" :') Hahaha. This man is awesome though. It's like he realises my attention span drifts and he repeats everything so I snap out of it and come back in time without missing too much.
Think of Efferent as Exiting from center. Efferent = Exiting.
(Afferent is going in.)
You can remember it as A for Aproach and E for Exit
dragistar Perfect....thanks so much :-)
Afferent=arriving.
Efferent=exiting.
Thats how i remember it.
+Seybora Bangtangotexomark Ahhh, come in. Eeeee! Get out!
Great lecture! Very clear and informative!! Thanks for posting
Oh my goodness, I finally understood this stuff after watching Bozeman, Crack Bio, and Khan Academy. Thanks!
You're videos are what make me go from a 89.9% to a 90.0%. Legend...
here is something that will make it go to 90.5%
It is supposed to be "Your" and not "you're".
omg ... 1 million views... that means i m nt the only one xD
Adi Sh me toooooooooo.......
Adi Sh Nice Video! Forgive me for chiming in, I would appreciate your initial thoughts. Have you ever tried - Trentvorty Perfection Kidney Theorem (probably on Google)? It is a good one off guide for improving kidney function minus the headache. Ive heard some unbelievable things about it and my old buddy Taylor finally got excellent results with it.
You made it so clear to understand!!! Wish ALL instructors were so clear!!!!Love this video!!!!!!! THANK YOU!!!!
thank you SO much! I have a final tomorrow and was very confused by how my professor covered this topic. I feel so much more confident going into my exam now. You're awesome :D
hey guys if you're looking for help in anatomy check out "Wendy Riggs" channel.
she really makes anatomy and histology simple and fun.
BASED KIDNEYS
I loved this video....I usually find anything renal-related boring, but this was so well-explained and his tone and way of explaining kept me interested. Thanks!
truly one of the best videos I have ever watched on youtube about urinary system.. thanks a lot
Wait...then how does vasa recta help in absorption?
What is the counter-current mechanism?
Do you have another video explaining that? O.o
no. stop. I just started understanding this, you're confusing me again...
''later excrete when we find a suitable time" lololol
This literally is going to help me for my test tomorrow! I understood everything but the order of blood flow within the kidney
Thank you! I watch your videos before reading my physiology book, and it makes learning much faster!
amazing!!!You helped me so much studing for paramedics final tests!!
10 times more helpful than 4 hours of lecture and lab combined!!
you explain most concepts way more than most lecturers do...thanks a lot!!!!!!
I love the way you say "loop of Henle" in an epic way. This video was very helpful!
Wow you have made this so interesting, fun and easy understand. Thank you a thousand times!
Could not be more grateful to you. Thank you so much. I can't believe how much more clearly you have explained this than my anatomy/physiology teacher. You are a lifesaver.
this is my 1st time being able to really understand anatomy. thanks to you!
you're way of explaining is unprecedented. thanks sal
This video was brilliant!!! Im at university and the lecturer didnt even explain it as well as you! Thank god for your videos.
This video is awesome and would be great to include on the MCAT prep site as well! It has a lot of important info that was missed in the Renal System lectures.
Great video, best explanation of the nephron that I've seen. Thanks for helping my studies!
you're my saviour Mr. Khan! If you made a video of every topic I study in bio class. You explain everything in a quarter of the time it takes for my lecturer to AND you make it so easy to understand! I really can't thank you enough and I'm sure a lot of people feel the same way.
SO helpful! Gonna ace my anatomy test tommorrow now! Thanks!!! :-)
Oh my gosh! Thank You! This was SO helpful! I wish I had found you at the beginning of the semester! I currently have a professor that doesn't teach but "reads" to us from the book! Thank You!
Thank you SO much for doing this. This made what I read make so much more sense. You are very good at what you do. I wish I would have found you early this semester for my A&P II class!! I will be referring to you in my further education...thanks again!!!
so clear now...thank you:)
Literally, this is amazing helps out a lot when I have science competitions and I need to know about a large scope of items! Thank You SO much.
Thank you for the great video!
To avoid confusion, the descending limb is not ONLY permeable to water it is also partially permeable to ions but for the sake of explaining, he simplified the concept to make it easier to understand.
Your videos are so incredibly helpful!
I've been reading the textbook again and again hoping to understand this process but this 18 min video made me thoroughly get it. You, Sir, is a legend
Khan academy rocks! Using this as a revision tool for my part 1 Emergency Medicine Specialist exam. A great, clear and concise overview. Thank you for making suck great quality education free to success for everyone :))))
I think it would be great if all teachers and professors were as clear as you!! That would make students' lives much much easier! You are GREAT! :-)
Very useful - worth the watch.
Omg Sal, do you really know everthing. I'm amazed! Youre amazing!
This makes so much sense. Thank you!
You just made my MCAT studying so much easier…THANK YOU!
Great job! It helps me to understand the concept more clearly than my teacher did in class.
excellent tutorial on the nephron! thank you very much!
Great video, lucky to watch. Solved my question.
Oh, my freaking god. I spent 3 hours in lectures and learned more in 20 minutes of your CZcams video.
Thank you!
Wow. I'm new to the whole Anatomy Physiology thing and I found kidneys to be somewhat challenging. This was so comprehensive. Thank you very much. Nicely done!
these things are much more easy to remember once they make sense. thank you!
Perfect. Thanks, be blessed.
GREAT video as always. You sir have changed the world for the better!
Sir you just made my life at least 5 times easier. Keep it up. Very comprehensive. Short and sweet unlike my lecturers. Thanks again
OMG thank you so much! you helped me finish college last year and this year you guys are hopefully helping me to pass my year 1 pharmacy exams. thank you for all the work you do.
