The Nephron - Ultrafiltration and Selective Reabsorption - GCSE Biology (9-1)

[@awppenheimer]

This makes _so_ much more sense now because you have given it context. Thanks!

[@alisonperez3353]

I'm 26 studying for the GAMSAT exam and i just wanna say "a massive thankyou sir". You taught me Photosynthesis, calvin cycle and kidney. You made it so easy to understand! God bless you! My exam is tomorrow x

[@MrExhambio]

That’s brilliant! Glad you found them so useful. Good luck in the exam, I’m sure you will smash it!

[@sophie4042]

Thank you so much, you explain it really well :) I'm using it for A level biology. I was just a bit confused at 4:20 - the bit about the water, where is the high concentration of the salts and where does the water diffuse out from and to where?

[@paraskunwar5081]

The medulla has high concentration of salts and solutes which causes the water to diffuse out of the left tube, and as water has exited henle's loop, the Na and Cl ions diffuse out of the right tube of henle's loop. It creates a cycle as such.

[@icyyyy3734]

how did you dooooo

[@masoso7351]

Thank you so much

[@georgefoord475]

thanks so much makes it very easy to learn

[@banansalih9284]

What do you mean due to low water potential, more water is reabsorbed? If there's more water in the bloodstream than medulla, then shouldn't it move out by osmosis? Also, my teacher mentioned that water is actually reabsorbed by the collecting duct, but it passes through tissue fluid in the medulla first, that's why there is efficient absorption, THEN it goes into the bloodstream.

As selective reabsorption occurs by diffusion, why wont Urea diffuse out aswell?

[@akashkulkarni1024]

does the RBC's and WBC goes into the nephrons or the efferent aterioles?

[@MrExhambio]

They go into the efferent arterioles. Too big to pass into nephron during ultrafiltration

[@fathimaihshana4945]

Sir, which blood vessel seems light colour(blood) in kidney

[@dhreyaoops3455]

aren't the glucose and amino acids absorbed through active transport?

[@MrExhambio]

Not directly no. The glucose and amino acids are cotransported with sodium ions down a gradient into the epithelial cell of the tubule then they diffuse from there into the blood. You need ATP to maintain the sodium concentration gradient for this to continue but they are not actively transported themselves.

[@Wasteman365]

In the description, it says water is reabsorbed at the collecting duct but I thought it happened at the Loop of Henle

[@yaasinalikondeth6724]

It happens at both. So it is absorbed in the Ascending loop of Henle. But because it passively absorbs, there's a chance that some water molecules didn't get reabsorbed. So in the Collecting duct, IF the body needs water or is in need of water, then water will be reabsorbed in the collecting duct, leaving only Urea (known as Urine now) and perhaps some mineral ions. So it basically gets reabsorbed at both places

[@jpsokk]

i’m still lost 😭 someone explain what ultrafiltration does??

[@myeahehe7378]

so basically the body needs to release waste substances such as urea, excess salts and excess water, as an accumilation could be harmful for the body. It does this by filtering ALL the substances in the blood (such as glucose, urea, water, ions) by pushing them out of the Glomerulus and into a cup structure called the Bowman's Capsule. Keep in mind that they only release substances small enough to go through the capillary, as other things like Red blood cells and white blood cells are too large to fit through. Because we dont want to excrete useful substances (like glucose and alot of water), the kidneys reabsorb them back, in another process called selective reabsorption Ik that was alot but i hope it helps
