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

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
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.
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.
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 !!!!
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.
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.
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!!!!
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!!!!
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.
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
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 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
"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.
i hope someone sees this comment soon, but since we are getting rid of a lot of water from the nephron and even more going down the collecting tubule, then how does our urine still contain 95% water? where does this water come from ?
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.
Can I have a question? When water leave the tubulus and go to medulla, what happen with the water? I mean when is too much water in medulla, it started to be hypotonic (it will be less concentrated). Are there some capillaries for transport the water out ?
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 🇨🇳!!!
i need some help. At the proximal convoluted tubule, water begins to reabsorb, but in the descending part of the loop of Henlé, does the water move out again? Also, i didn't understand clearly what the 2 functions of the loop of Henlé were. Thanks
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. ❤🙏
Nephrons are the functional unit of the kidney. You can also call it renal parenchyma. Not really sure what part of the video you wrote that in response to, but he's correct in calling the nephron the smallest functional level of the kidney.
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.
I have been doing well in my class but all I have been doing is memorizing the textbook and regurgitating it back when I take the exams. But by watching your videos, I actually UNDERSTAND the material. It's really sad that college students all around the world are paying hundreds of thousands of dollars and not learning anything.
dump = DESPEJAR kidney = rim liver = fígado electrolyte = eletrólito (a liquid or gel that contains ions and can be decomposed by electrolysis, e.g., that present in a battery.) duct = duto ureter = the duct by which urine passes from the kidney to the bladder or cloaca. bladder = bexiga cloaca = a common cavity at the end of the digestive tract for the release of both excretory and genital products in vertebrates (except most mammals) and certain invertebrates. The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract) Tract = trato Jam = geleia ou esmagar, comprimir capillary = capilar afferent = aferente [adj. Que conduz; que leva. Anatomia. Diz-se dos vasos (sanguíneos especialmente) que se lançam em outro ou chegam a um órgão, ou de um nervo que transmite um impulso nervoso a um órgão ou centro correspondente.] windy = ventoso ou (of a road or river) following a curving or twisting course. venous = of or relating to a vein or the veins squeeze = aperto, compressão porous = poroso, que tem poros Convolute = convoluto (Enrolado em forma de cilindro: folhas convolutas) picky = exigente, meticuloso pump out = bombear (no caso, bombear para fora) tidbit = petisco jut = saliência ou salientar dip = mergulho, mergulhar reddish = avermelhado secrete = segredar, esconder distal = situated away from the center of the body or from the point of attachment. chute = a sloping channel or slide for conveying things to a lower level.
PSA: It is slightly misleading when you say only a little bit of H2O leaves the proximal tubule because about 67% of the filtered water is reabsorbed into the peritubular capillaries.
This video does not explain thing of practical importance. In regards to water, salt, blood pressure relationship, back flushing of the filtration system. Still leaves much room for wild hypothesis. Like would drinking a huge amount of water help backflush, clean filter, lower blood pressure via less hormone signaling-making the filtration go easier?.... Seems like too little salt would make kidneys work harder, by watching this. But, I doubt this is true in reality. Something isn't right or complete with the model.
Great for 99%, apart from concentration at DCT which isn't very concentrated at all. Mostly reliant on collecting duct, just look at diabetes insipidus
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
Good Information, my friend has suffered from this problem. Then Someone told him about Planet Ayurveda, he went there and took treatment. Now he is Totally fine.
mahen3791 - I think the ions/water in the interstitium from filtering out in the Loop are picked up by the Vasa Recta, the vasculature that dips down around the Loop of Henle from the efferent arteriole.
Got past my Alevels I don't think I ever understood what a nephron was lol , and now doing my Bachelor of Science in Nursing and watching this 18 min video I now know what it is hahaha
I had to stop this video for a while to give a huge THANK U before resuming it, i cant believe that our educational system its so terrible that paid teachers cant explain things at this level . ( so be thankful to NOT live on underdevelopment countries as i am, that i have to search for info on the internet)
I just don't understand....... These seem to be sooooo hard and seeing the comments I can say that these are taught to college students but we are learning this all in class 7! Btw thank you, this is really helpful. I hope I am gonna top this time.
These videos cater to a variety of tests like AP, nursing, school/college and then the videos are collected and then dumped under MCAT. These are not dedicated videos for MCAT. The end result is a lot of fluff not needed for MCAT and in kidney terms this needs to filtrated. Too much nonsense
