At 14:55, why would all of the sodium ions being actively transported out of the Loop of Henle mean that when the filtrate reaches the distal convoluted tubule it is dilute? Because as the ascending limb of the loop of henle is impermeable to water, wouldn't that mean that there is no opportunity for water to escape?
Because in the ascending limb, solute (Na+) decreases while the volume of solvent (water) remains unchanged due to the water's impermeability, therefore the dilution (If you don't study chemistry, concentration is calculated by mole/volume)
Hi Miss Estruch, Im a y13 student doing AQA exam board. Ive also got Selective Reabsorption of water as well and I think you might have missed that part maybe? Other than that everything else in this video has helped me understand alot more about this topic
Hi, Miss. A bit confused by point 4 at 13.44mins. Do you mean concentrated solution due to all the water that has moved out? Sorry to be a pain. Just trying to get my head around it. The videos are super helpful.
hi miss estruch , amazing video i just wanted to ask at 13:37 if water was to move out of the ascending limb wouldnt there be a concentrated solution ??
Walls of ascending limb r impermeable to water so water doesn’t move out. However sodium ions r actively transported out so it’s less concentrated ie high water potential
The kidney is such a daft organ; it's like deciding you want to get rid of all the bits of dirt in your house & putting every single thing that is small enough e.g. food, remote controls, cutlery, clothes etc out through the windows out into the garden & then deciding to put everything useful back except the dirt particles. Evolution is not perfect, is it!
Thank you! It’s amazing how much information you can impart in such a short time.
ah thanks!
KEEP UP W THE VIDEOS!! you're helping hundreds of kids like me not only pass their alevels, but helping us work towards our A*'s!!! thank u
Thanks.
You are really of great help. Am in year 13

wonderful explanation and a very amazing A level teacher Thank you very much!

Hello miss, is there video on the loop of henle counter current mechanism? Is it required for aqa?
This evoked memories of my highschool
Good ones I hope!
@@MissEstruchBiology indeed Miss
Cry then
Cry puffy

Thank you very much. Thank god I found you 😊
so pleased it helped
Thank you for the video, it is really detailed and easy to comprehend.
Glad it was helpful!
Hi I can't seem to find the osmoregulation video you mentioned, could you possibly drop it's link
Thanks Miss Estruch for the updated version ❤
😊😊 hope it helps

I actually have my federal board biology paper class 12 and this really helped❤❤
Good luck!!!! Glad it was helpful
Do we have to know about podocytes in ultrarfiltration or is it extra detail?
yeah, podocytes does come up on mark schemes sometimes
hiya whats the difference between this and the other nepron video
I added in details about the basement membrane and podocytes
@@MissEstruchBiology thank you for updating :)
thanks this made me understand the topic more
Yay so pleased 😊
Mam I requested you to arrange lectures by chapter for easy topic search.
hey, they are if you have a look at my playlists
Thank you!!
You're welcome!

Cry me a river mate
yay super helpful thank youuu
Happy to help!
at 0:31 it seems you spelt collecting as ‘colleting’ so yeah spelling mistake maybe
thank u so much
You are most welcome
Coming back even I enter the uni 😂😂😂😂
hey 👋🏻 welcome back
