I like how you just summarised topics that were taught 2 hours in the lecture hall in less than 20 minutes !! Thank you so much
Armando, I can't thank you enough for these videos. You have an incredible way (through your explanations and drawings) of making complex topics seem simple. You rock man!
you should certainly consider a future in teaching. Your videos are outstanding. Thank you so much

I love you
Your videos are great. Straight to the point without useless jargon. Thank you.
I love your videos man. Very thorough. Beautiful Artwork as well. I really like that you repeatedly repeat the name of the structures as you draw them because it helps solidify the picture in my mind. So don't Apologize! Thank you again!
Your explanations and drawings are simply the best. Thank you!
i'm a secondry school student and this is just WOW! you are really helpful please keep posting vids cos ur a great teacher and you help us a lot. thankyou
Hi Armando, Thanks for the videos. They are excellent.
I just have a couple of issues with this particular video.
Firstly, you refer to the glomeular filtration rate as being 10mmHg. That is the glomeular net filtration pressure (not rate). Secondly, you mention the glomerular hydrostatic, bowmans capsule hydrostatic pressure and bowmans capsule oncotic pressure. You should probably also note the glomerular capillary plasma oncotic pressure too and add that into your equtaion.
Thanks!
+Danni Volling-Geoghegan
I think you mean to say that he should mention the Bowman's Capsule oncotic pressure. He DOES mention: 1) Glomerular Hydrostatic Pressure, 2) Glomerular Capillary Oncotic Pressure, and 3) Bowman's Capsule Hydrostatic Pressure.
However, many people omit the Bowman's Capsule Oncotic Pressure because, under normal circumstances of a healthy functioning kidney, there should be NO protein in the Bowman's Capsule, and thus the Bowman's Capsule Oncotic Pressure is considered negligible. I know what you mean about including it just to be thorough, but it's not necessary in this case, since he's not discussing a diseased kidney specifically :)
In a healthy nephron environment, the Bowman's capsule oncotic pressure is effectively 0 mmHg, so the equation is often simplified to remove it which is probably what he was doing.
Thank you so much for your wonderful videos Armando! I would have passed advanced A&P but because of you I earned an A :)
Caroline Nicholson I love you
Hi Armando the videos are really good. Where can i see the continuation video for reabsorption and secretion of the kidney, i cannot find it within your channel.
Jose A Cintron Vazquez did you find it?
Thankyou thankyou thankyou thankyou thankyou thankyou thankyou thankyou... Can't thankyou enough. No matter how hard I tried I was never able to understand renal physiology before. Thankyou once again
Thanks for making these videos and its so helping. Please do post the reabsorption and secretion video..
this is helping me so much! love the way you are able to explain the details of the physiology while making sure you hit the most important parts of the anatomy at the same time. the style of the videos are great and I am amazed at the time and effort you put into creating them, it's wonderful and thank you
you know what my doctor saw your video and put the questions Dependant on what did u said , I was just getting bad marks like 55 % then when I saw yours video , miracle happened believe me I got 80% next exam ! 😊
These are incredible and also very high quality videos.Thanks for sharing .
Hi Armando, I love your videos! Thanks so much for making them. Your clear drawings and explanations help a lot. My professors in PA school are great but this really helps fill in the gaps. I'm wondering if you plan on posting the reabsorption and secretion videos at some point? I see they are not here nor on your page. Thanks again for all you do!
all the three Nephrology's videos are AWSOME, very very helpful and amazing,thanks for free sharing of your knowledge in such a beautiful artistic way with us.
Thank you SOOO MUCH! I study guide has made a mistake and stated that "Decreased Hydrostatic Pressure in Bowman's Capsule increases the GFR." Must have been a mistake. I would have never caught that if not for your video. You're Awesome.
+Neo Ayeri this is actually correct! Hydrostatic Pressure in the Bowman's Capsule is the same as Bowman's Capsule pressure! therefore a decreased value would promote filtration from the glomerulus into the bowman's capsule. Remember Hydrostatic Pressure in the Bowman's Capsule ISN'T the same as Hydrostatic Pressure in the Glomerulus!!
You're going to help me ace my Physiology final. You are great
Seems like you havent upload the video about reabsorption and secretion. Am I wrong?
I do really hope you'll upload it soon. Thank you so much armando!
i too
+wiryantari akhdani Pratiwi I know! I wanted to watch those ones so bad! :(
ruclips.net/video/ko_XD4jPEo8/видео.html
watch it reabsorbtion and secrection new vedio by Armado
Wiryantari Akhda
I love you
You pronounce the words so much different than me! I love it, somehow hearing it differently makes it easier to understand or something.
thank you , short and straight to the point
OMG I wish you uploaded the reabsorption and secretion video! This was sooooo good man!
this guy saved my career. thank you so much!
what the hell, i didnt expect your video to be this good. Thank you so much! i really do hope you continue to make videos like this one :)
Thank you, Armando, from a cross the globe!
So that we can look at your notes as an overview,could you possibly post a picture of your finished drawing+ annotations on your social networking sites?
Where is the reabsorption video? Please and thank you!
Armando!!! You PROMISED videos on reabsorption and secretion!!! I neeeeed these in the next week!!!! Annnnd go! Thanks
is there a video on the JGA and Macula Densa and how they regulate Systemic BP? and also what about what is reabsorbed at each section of the nephron?
Afferent artirioles are the arteiroles that flow TOWARDS the glomerulus, while Efferent artrioloes are simply the ones that carry blood AWAY from the glomerulus. Thier position in the diagram shouldnt matter, just which way the blood is flowing.
I remember which is which by Afferent starts with an A and is first in the alphabet, and thus the blood flows from A to E(fferent)
Hopefully that makes sense to you :D
Sweet video. When you are talking about the GFR (glomerular filtration rate) you said the equation was GFR = Kf x Net Filtration Rate of 10 mmHg. Was that supposed to be kf x Net Filtration Pressure.
your videos are so good please do upload the continuation of this video as soon as u can ..
Thanks for sharing. I really appreciate your work
not sure if i missed a video of you actually showing how filtration works its way through the glomerulus all the way until its expelled out of the body, reaborption and secretion being involved...can you send the link to me under my comment, please?
What a great video! Is tubular re-absorption coming?
why increased afferent arteriole resistance decrease G,Hydrostatic pressure instead increasing it? Isn't vasoconstriction increases blood pressure in general?
Armando you are the best on youtube, Thank You!!
It s very cool. If i learn with your vid last month, i will get better score exactly. thank you so much.
Awesome video, please upload the reabsorption and secretion ones too
I am grateful for your videos. They will help me a lot in my final!!!!
thank you so much for all your videos, they are REALLY helpful. it's easier to understand with illustrations. i plan to watch all your videos. thank you for your handwork :)
this is very useful, please make a reabsorbsion and secretion part
Can you do a video on renal physiology in regards to what happens during exercise? Studies show an increase GFR from 120ml/min to 135ml/min at 25% of VO2max which is interesting because of the decrease of renal blood flow. So how can GFR increase if there was a decrease in renal blood flow?
yes please..where is the reabsorption video?? i can't find it..i really need it ASAP..please reply me..
muhammad ikram it’s been 5 years , he didn’t reply yet . 😂😂😂😭😭😭
@@astha.floydd5929 hello 😂 he did
zekzi mbappe 😂 omg really?
@@astha.floydd5929 he didnt reply but he did upload 😂
i am literally laughing and crying at the same time while watching this video. the former because the way you tried to pronounce glomerulus is so funny, and the latter because i finally understand this part of nephrology! THANK YOU SO MUCH! i'm still waiting for the reabsorption video tho.. and can you PLEASE make one on countercurrent multiplication system?
amazing explanation sir
thanks for these videos, are awesome. Hugs from Brazil
Where is the reabsorption video! :/
what if you dilate Efferent? would that decrease GFR as well? DA/CD => UP GFR, CA/DE => DOWN GFR (Constrict = C, Dilate = D, A = afferent, E = efferent), can this generalization be made? thank you for the video!
How is glomerular ultrafiltrate isotonic to plamsa?
Ultrafiltrate should be hypotonic to plama as it does not have albumin.
???
Hi, thanks in advance to anyone who answers my question!
As GFR is a measure of kidney function, a decreased GFR essentially means reduced kidney function. Would it be correct to say that a lower Kf (in GFR calculation) would be a mechanical injury to the kidney (e.g loss of nephrons from neoplasia, CKD etc) and a decrease in GFR due to abnormal net filtration rate would be a metabolic injury e.g abnormal hormone regulation, starling force disruption?
Does anyone Know how GFR is used clinically?
Thanks
Hey Armando! Are the videos about reabsorption and secretion gonna come out one day? :)
Awesome work on this video! thanks for the help!
Hello Armando as you know Chloride is Negatively charge and the Basement membrane is negatively charge so How Chloride can filter 👍
if i don't resonate with this content, should i not take biomed?
Where is reabsorption and secretion parts?😟😟😟it was going so interesting learning through video then suddenly no continuation😒😒😒😒
Can u please upload remaining parts??
I thought I was the only one finding it funny to pronounce the Gromerula or Glumerulus, I don't blame you hahaha. Great vid.
you are fantastic.its really helpful.
please also mention the reference of book so we can read to strong our concept.thankew
when he says less than 1% is actually excreted in the beginning some materials are also secreted from the blood vessels back into the proximal tubule so isnt it more than that 1%?
The amount that is secreted is very less for that 1% to get altered
Great video, thanks for making !
U made a mistake I think juxtaglomerular apparatus form by afferent arteriole and distal convulating tubules not thick ascending limb. Alright?
Excellent video..Thank you Armando..
I was so confusing about renal physiology, not until i found your videos :) Thank you so much! but how come I can't find the continuation? I hope you will upload it soon :)
wheres the next video??
Do you have images of the finished drawings that you make available for download? They are great! Thanks for these videos!
they are in the links section as a google doc picture. can be printed from there
why is afferent and efferent artirioles different to my book?? i have afferent above efferent in my biology books. i have noticed this with other videos that it changes, which is the correct way??
First of all you are Amazing
But when will you upload videos about secretion and absorption
amr elshaer no video of secretion and absorption
So helpful! Thank you!
I don't get it why increasing Raff we dicrease PGH.. dont we increase it bc the diameter dicreases so the blood leaves with more pressure the aff arteriole to the bowmans capsule??
thanks a lot all your presentation were pretty awesome and helpful
Hi! You're videos are great! Could you please post the link for the secretion and reabsorption videos, can't seem to find them on your channel :) Thanks
Can someone explain why an increase in resistance in the afferent arteriole causes a decrease in glomerular hydrostatic pressure?
hello! can you please tell me where i find the reabsorption and secretion Videos? thanks!
This is really helpful, thankyou- when will the videos on re-absorption and secretion be up?
@Armando Hasudungan Brilliant video as always. Starting nephrology soon so as a review this was awesome! Just wanted to ask why you used the Net filtration rate in the GFR equation, instead of the Net filtration Pressure that you had described just prior to showing the GFR equation. Was a bit confused by this. Thanks again!
I love all your videos !
great explanation! thanks so much
is the nephron a node? considering polarized exchange or not of serem
its beautifully explained. thank you so much
hello. are there videos for reabsorption and secretion?
Truly an icon
Thank you for your videos! you saved me form physiology
Do you mean capillary hydrostatic pressure when you say glomerulus hydrostatic pressure?
Thank you Infinitely!
Thank you so much
Thank you so, so much for your work. Seriously, you are awesome!
Thank you so much very helpful video
Hi sir..your videos are really good and understanding..sir I couldn't find tubular reabsorption and secretion in your total channel.. please do upload sir.
Very informative. Thank you!
Excellent way of presentation. Luv u 💕
Great video as usual, keep it up the awesome work
because it is very small even it is negatively charge they can still pass through >>>he said this in 5:53
Where is the reabsorbtion video? thanks its help me a lot
Thank u 4 the amazing videos but can u please do one for renal fraction
thank you so much sir!
thank you very much
wow! im saved by you!
i just have a question, does the decrease in the efferent arteriole has any effect in the glomerular hydrostatic pressure ??
Yes
Hey I was just wondering, do you have a video on the sliding filament theory? I found your myology videos very helpful but couldn't seem to find the sliding filament theory video you referred to!
Good work
can you pls explain what kind of pressure that makes re-absorption process happens?
