This is the best video i have found for renal clearance on the internet. You really explain the in-depth of renal clearance, everyone else just glosses over the definitions without explaining the 'how' and the 'why'. I have learned a lot from this channel and I hope to learn even more from you.
Thank you so much. You made my day. I am so happy to help
Thank you so much mam.
The best video for renal clearance in you tube. I was just memorising the formula and definition without understanding. Searched for many more videos at last I found it.
So so happy to help
Truely the best tutorial available for renal clearance , you have explained it in the best possible way .
Thank you so much…😊❤️
I love studying with your physiology videos been having difficulties understanding renal clearance. Thanks for making it easier to understand.
Journey started from learning tech - was made fun of - and now I just love teaching concepts - validates when I get messages like this. Bless you
WOW WOW WOW JUST WOW no formula clear logic and everything explained in detail truely the best video on internet on this topic thank you so much maam !😇🥰
Glad you enjoyed it!
This is the best channel for physiology!!
Thankyou…do like and share
Today I was very happy that after a long struggle I cleared the concept.Best video for clearance
Thanks mam
My pleasure 😊
Wow ma’am real thankful. I recently discovered your channel and since then, I don’t search the topics by name, I rather search “Topic Physiology Open” Because not only your concepts are super clear, but also they are short videos which saves time. So thank you so much, really grateful, plz do keep making videos.
Oh my God !!! absolutely delightful. Feel like i am serving the purpose
Thaanks a lot ma'am!!!!
My pleasure
Creating new account just to subscribe your channel Great job
Ohh...that is so nice. Very glad
Ur concepts r crystal clear
Thank u mam🥳😍
You are most welcome
Wonderful explanation
Thanks. Glad you liked it 😊
My physiology motivation ... thanks mam❤️❤️❤️
So so glad...thanks Awais
Mam you are welcome
Mam I have a question , in autoregulation of GFR it is stated that increase in BP will increase perfusion pressure hence increase in GFR but to regulate the GFR , afferent arteriole constrict that decrease GFR but in the same time in Long term BP control , there is rise of BP , and subsequently rise in GFR but here the GFR not reduced ... Why !!? I mean in both the cases there is rise in GFR but in autoregulation GFR is maintained but in BP regulation instead of increase in GFR , GFR is not reduced ....
Thank you mam
You are most welcome
ma'am what's the difference b/w gfr and clearance rate... also how much plasma leaves the kidneys? is it 650- gfr?
Question is not clear - Can you elaborate
Excellent
Cleared the logic which is bothering quite sometime
Kind regards
Vara Prasad
I know!!! Glad you liked it
great job. highly appreciated!!!
Thanks...keep learning
Loved the video.♥️♥️. I have some doubt though.
1. Why do we need a substance PAH which gets secreted & not Inulin which gets 100% filtered, for calculating RPF ?
2. After which point in circulation RBF becomes RFP ? Or is it just for calculation purpose to remove RBC ?
Filtered means ..it will check the percentage of plasma which is getting filtered, since only that much percentage of renal plasma flow is getting cleared of the substance. For RPF , we want whole plasma to get cleared of the substance. That can only happen when the substance is filtered as well as secreted
2. Since RBCs don’t get filtered and actually they are part of plasma only. So basically plasma is getting cleared of the substance. If there is a substance which is present inside RBCs as well as in plasma and both RBCs and plasma get cleared of the substance, then the substance will actually determine Renal blood flow.
This is not the case with PAH
And thanks for intriguing questions
@@PhysiologyOpen thank you mam for clearing the doubt & such a timely response. Your presentation & explainations are really good.♥️
Outstanding mam.. thank you so much!
My pleasure 😊
Thankyouuuu soooo much ma'am
Can't thank enough actually!!
My pleasure always
Well explained
Thanks
Mam you said that we can use this formula(Cu×V/Cp) only for substances which are freely filtered,
But doesnt clearance means volume of plasma completely cleared of a substance , it can be cleared by filtration, reabsorption or secretion: so we can include them too in clearance
So when we will use this formula, say in case of secretion: the value of clearance which we get will tell us about(filtration + secretion)
Isnt it right??
No we can use the formula for calculation of tubular fluid concentration when the substance is freely filtered..
This formula which you are asking can be used for clearance..so yes you are right
@@PhysiologyOpen understood mam thank you
Thank you ma’am
You are welcome
UV ... Excretion Rate/P=== Renal Clearance
Renal Blood Flow=Renal
Plasma Flow/Serum Plasma(1-Hct)
Secretion=Excretion - Filtration
GFR= (Pg-Pb)-(πg-πb)/Creatinine or inuline clearence
Renal Plasma Flow .... clearence of PAH...ERPF/ER
FF=GFR/RPF
Thanks for sharing
Thank you 😍😍
Most welcome
