Structure of the NEPHRON- A-level Biology. Ultrafiltration and selective reabsorption in the kidney

Learn the structures of the nephron - renal capsule, proximal convoluted tubule, the loop of Henle, distal convoluted tubule and the collecting duct. Learn how and where ultrafiltration occurs, selective reabsorption and how urine is formed.

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

[@Anonymous-nr4iv]

Thank you for the video, it is really detailed and easy to comprehend.

[@MissEstruchBiology]

Glad it was helpful!

[@DanielWhite-lr9kl]

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?

[@Anonymous-nr4iv]

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)

[@ManjulaRathnayaka-ql3ji]

thank u so much

[@MissEstruchBiology]

You are most welcome

[@sabriya5219]

Do we have to know about podocytes in ultrarfiltration or is it extra detail?

[@MissEstruchBiology]

yeah, podocytes does come up on mark schemes sometimes

[@aqsakhan6946]

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 ??

[@aa-gn6zn]

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

[@hafsaahmad2771]

I actually have my federal board biology paper class 12 and this really helped❤❤

[@MissEstruchBiology]

Good luck!!!! Glad it was helpful
