Great explanation, really appreciated the continual focus on the overall goal of each nephron segment. Made it much easier to understand and therefore remember. Thanks!
Great video, thanks... just one thing=The hormone IS called AHD, it ussed to be called vasopressin because it was first discovered in the contraction of capilars, but its most important effect is in the nephron, so they are slowly changing the name to ADH.
The distal convoluted tubule is controlled by the hormone aldosterone which stimulates the filtrate to reabsorb more Na+, when the blood pressure is low. This increase in Na+ stimulates ADH to be secreted which stimulates water to be reabsorbed into the blood. More water and salt in the blood creates an increase in blood volume which in turn increases blood pressure. I hope this answers your question.
thank you so much. 20 pages in 10 min. good job. Now it will take just a hour to read these pages for putting into my mind forever. :D when you understand something well, the life is even simpler. thank you again so much
I have to say I understood evrything becouse of you! the profesor in my university explained it in the class and i didnt understand it, then i tried to understand it myself and couldnt.... only when i saw this everything came togerther Thank you!
Thank you so much for this great video! It helped me understand this material that I've been reading over and over. I just could not comprehend the process, but now it's so clear to me!
Well you need to remember that water is reabsorbed into the blood. Because water is getting out and going back to the blood, it is not staying in the "environment" of the medulla. The water is gone! As water leaves, the filtrate gets more and more concentrated. Then after the bottom of the loop of henle, at the ascending tube, as you said: ions are reabsorbed intoo the blood, which causes the osmolarity to go back down since you have less and less solute in the filtrate. I hope this helps! :)
5:40 - 5:59 Can you explain this please. Osmosis is not allowed to happen; If osmosis happens, the osmolarity will be decreasing as we go higher in the tube. Isn't this what's happening ?
thanks for the explanation..was very simple and straightforward ..I don't understand why in school the teachers i have make everything so complicated...
Sorry!!! I'm busy enough with general biology, A&P, human physiology and this RUclips channel!!! But I'm glad you find the videos helpful and I wish you luck in pharmacol (I know it's tough...) :)
She's correct actually as she is saying that the kidneys filter 20% of cardiac output and >19 of these % are being reabsorbed. You are also correct in saying that >99% of the filtrate is reabsorbed, however that is equivalent to saying that >19% (>19/20 ~ 99%)of cardiac output is reabsorbed after passing through the kidneys. Just confusing terms thats all.
Thank you so much..you made it short ,simple, and sweet.I wish my Professor explained like this, i think he just hates us..lol..anyways THANKS AGAIN HAPPY NEW YEAR
Hi Prof. You are definitely a very intelligent person with a diverse range of interests. Great videos (about all topics that you choose to "shoot" them). Was wondering about your medical videos: Would you be kind enough to tell f from where do you use the diagrams from? These are real great figures. is there any copyright issues involved? Apologies for a string of questions. Regards
You will make a great mother :) Awesome explanation, as if it were not science, but a pleasant bedtime story. Great voice. Thanks for posting it here ;)
Hey in the diagram at 6:31 , shouldn't the blood flow in the vasa recta around the loop of henle be like in the opposite direction .and not like its shown here.... plz clerify :)
I will definitely make use of this video when I need to help students understand the loop of Henle and the role of renal functions in regulating bodily osmolarity. Great content, concisely stated, with clear visuals. It would be hard to improve upon this production. Hats off to the PenguinProf!
if water is getting out in the descending part,and ions are getting out on the ascending part,,why doesnt the osmolarity stay the same??? I dont understand !! can someone help me please? thanks
Wow! This was a really amazing and clear video :) I didn't have to know about vasopressin and the physiology behind that but I learned it anyways haha :) Thank you!
Knowledgea Costanzo Physiology is the medical school standard, and she authored the BRS: Physiology review book based off of the textbook. I would definitely use that
Dear prof, I was wondering if you can please tell me how does the water that moves out from the descending tubules get "reabsorbed" by the blood, since the blood has a lower osmolarity. The water will supposedly like to stay in the interstitial space because there's more salt there. Thank you so much for your amazing video.
hey i cant find the previous video. i cant find it on your channel either. can you please link it to me or on your channel. thank you so much i lover your videos btw :)
Awesome vid!! :) but - Oops, at the beginning there you referred to the filtrate as being blood 'filtered blood' rather than fluid. Blood is just in the cap's.
You have absolutely made a big difference in the lives of the people watching your videos including myself. Thank you so much.
I spent ages looking at the book and being confused but 9 minutes watching this has made it alot clearer, Thank you.
I watched about 15 videos, and this one, by far is the best. You explain everything so nicely, wish you were my professor! THANK YOU
It's really easier to understand when thing are explained like here. Thanks.

Oh my god...I've got an exam on monday and the nephron has been hard for me to understand for months....this really helped thank you
As a 1st yr med student, i have to say that this short lecture was very helpful! Thank YOU!
I love how at one part the phone randomly rings! Your explanation helped a lot, btw. Thank you!
I'm so glad you found it helpful! You are most welcome!
That helped me far more than my lecturer's explanation. Thanks!
this is amazing, the beginning with the review on terminology was much needed for me. thanks a ton
Wow you teach really well. I appreciate all your help! I am taking college level Homeostasis and it is one TOUGH course
The distal convoluted tubule is controlled by the hormone aldosterone which stimulates the filtrate to reabsorb more Na+, when the blood pressure is low. This increase in Na+ stimulates ADH to be secreted which stimulates water to be reabsorbed into the blood.

then i tried to understand it myself and couldnt.... only when i saw this everything came togerther
Thank you!
OMG! That made things SO much clearer! Far better than all of the textbook/note reading I've done! Thanks so much!!
You just helped very confused paramedic student actually understand it! Yay, thankyou!
Thank you so much for this great video! It helped me understand this material that I've been reading over and over. I just could not comprehend the process, but now it's so clear to me!
You have an amazing teaching style! You break everything down so that I understand it and retain the information! Thank you!!!!!!
Most concise and informative video I have found on nephron function. Thank-you!
seriously, u explained it better than my physiology prof. thank u!
Wonderful!! i'm a medstudent and this vid helped me so much!! Thank you! keep on !!

i really like your voice , it's very comforting..and of course the way you explain things are very clear and easy to understand....Thank you!
Thank you PenguinProf : ) You explained this SOO MUCH better than my professor did.
The Vegas comment made this video that much better! Love it!
So glad to hear!
i love ur voice... i wish u were my teacher back then.
5:40 - 5:59 Can you explain this please. Osmosis is not allowed to happen; If osmosis happens, the osmolarity will be decreasing as we go higher in the tube. Isn't this what's happening ?
thanks for the explanation..was very simple and straightforward ..I don't understand why in school the teachers i have make everything so complicated...
you're so perfect i wish if our doctors were like you i swear i wouldn't skip a class thank you !
Thank you so much! You don't understand how much you helped me!
I feel EXACTLY like the keys to understanding are just out of reach and being held by some bizarre little robot thank you for understanding
bizarre robots are ruining my life!
It's really good now i understand
Thanks prof. This is something I've always kind of understood but not really had a good grip of. Good clear video.
this really helped for my renal module in med school! thanks so much.
Im so glad I found you... Just before the exams so THANKYOU!!
Can you teach my pharmacology class?! PLEASE?! You would make nursing school much more fun! Your videos help so much.
Sorry!!! I'm busy enough with general biology, A&P, human physiology and this RUclips channel!!! But I'm glad you find the videos helpful and I wish you luck in pharmacol (I know it's tough...) :)
One of my favorite places to review and learn! Thanks for breaking things down
Thank you, Thank you, Thank you!! If only you were MY physiology Professor!
Thank you for this! It was a great video to watch right before taking the MCAT. :-)
She's correct actually as she is saying that the kidneys filter 20% of cardiac output and >19 of these % are being reabsorbed.

Thank you so much for this video. You covered so many of the basics that I never understood and made it make sense.
What a wonderful video! Thank you for your insight! Keep these winners coming!
Thank you so much..you made it short ,simple, and sweet.I wish my Professor explained like this, i think he just hates us..lol..anyways THANKS AGAIN HAPPY NEW YEAR
thank you! i loved your video..one of the most descriptive explanations with regards to the nephron!
@Prathmesh77 she just means percentage points, not percentage of the remenant. Additionally she clarifies it later.
I can't believe it..you made it look so simple! Great job! Thanks:)
The best ever ! Finally i have understood this theme , I am speechless
I can't thank you enough for this video! Very clear and easy to understand!
This makes so much sense, thanks for helping out a med student.
That was fantastic!!! A great overview & explanation of the osmostuff that's going on!!
I really liked your presentation of the nephrons.. Thank you for making this video..
Same thing really. If you understand the diagram. Also it says MORE than 19% is reabsorbed. But you are correct!
Hi Prof.
You are definitely a very intelligent person with a diverse range of interests.
Great videos (about all topics that you choose to "shoot" them).
Was wondering about your medical videos: Would you be kind enough to tell f from where do you use the diagrams from?
These are real great figures.
is there any copyright issues involved?
Apologies for a string of questions.
Regards
Thanks :) Great explanation. I liked the pictures you used too. It helped me visualize the material better.
Outstanding explanation. Thanks!
+Andrew Lienhard You are so welcome! Thanks for watching!
You will make a great mother :) Awesome explanation, as if it were not science, but a pleasant bedtime story. Great voice. Thanks for posting it here ;)
Great video, definitely helped me out a lot for that MCAT.
I think chemistry would be helpful to get a greater understand of why some of these processes occur such as osmosis, and good luck
@thriceaweek Solutes are actively reabsorbed in the thick assending limb via the NKCC2 transporter :)
Wonderful teaching skills. Great voice and interest keeping. Thanks loads for your help...
Hey
in the diagram at 6:31 , shouldn't the blood flow in the vasa recta around the loop of henle be like in the opposite direction .and not like its shown here.... plz clerify
:)
where the salts are moving out at ascending lope of Henley? @6:39
Thank you so much..............Where sweet lady have you been all my educational life.....Very clear and easy to understand.
I will definitely make use of this video when I need to help students understand the loop of Henle and the role of renal functions in regulating bodily osmolarity. Great content, concisely stated, with clear visuals. It would be hard to improve upon this production. Hats off to the PenguinProf!
Khan Academy on RUclips has some very good videos on the nephron...
I like Khan Academy content in general; I was highlighting this video because it was the first I'd heard of PenguinProf and I like what she's doing.
You're a really good teacher..Come to UTHSC!
thank you....penguin professor! it will help a lot for my finals!
Is not 20 - 23 liters per day a great amount of work for the kidneys?
Thank you for this video. I'm studying for Step 1 and this was quite helpful!!
how does the kidneys regulate the production of vitamin d?
Omg. Come here so I can give you a big hug!! Whoopeee thanks for the vid!
if water is getting out in the descending part,and ions are getting out on the ascending part,,why doesnt the osmolarity stay the same??? I dont understand !! can someone help me please? thanks
Wonderful. So creative to memorize information. Thank you so much.
Wow! This was a really amazing and clear video :) I didn't have to know about vasopressin and the physiology behind that but I learned it anyways haha :) Thank you!
Thank you very much! Amazing job! Even German speaking person like me has understood the nephron-stuff now :-)
Well done!
Hi. Excellent information. Whats the reference book you use? Guyton doesn't have those nice graphics. Thank you
Knowledgea Costanzo Physiology is the medical school standard, and she authored the BRS: Physiology review book based off of the textbook. I would definitely use that

This coverd a lot of information I didn't understand in class, thank you!
Also I appreciate a lot of fuzzy bunnies :D that made me laugh.
Where did the blood go from DCT?
Thanks, I'll be sharing this with my prof and class if that's ok?
what about the distal convoluted tubule?
You explained so nicely :) have a test in two days and its definitely more clear to me :D
Now I can understand why we take Vassopressin antagonist as a Diuretic agent
thanks ...
Which text book did you use for the figures? Thank you.
These prof. is amazing.Thanks.
23 L/day can be a maximum urine production ? what are we elephants?
hey
i cant find the previous video. i cant find it on your channel either. can you please link it to me or on your channel. thank you so much i lover your videos btw :)
what does it mean mosm ?
Happy fuzzy bunnies gets me every time. Thank you!
It makes more sense now. I wish my teacher uses visual aids like this.
Bunch of thanks for this! I'm mostly understand this topic!
Awesome vid!! :) but - Oops, at the beginning there you referred to the filtrate as being blood 'filtered blood' rather than fluid. Blood is just in the cap's.
absolutely fantastic...... i wish you could explain everytn so easy way....
Oh how I wish you could come teach at my school :)
thanks for saving me my brain is exactly as you described for some odd reason its finals and my brain does not want to hold much. Yet this helped
+jonnay hardin I'm so glad it was helpful! Finals make everyone crazy... good luck with yours!!!
Excellent explanation of the content. Thank you!
You keep saying "osmolarity." Is that different from "osmolality"?
urinary system?
Thank you so much for the video. It really helps to clarify some concepts
Wow this video just saved my life
