My textbook had like 20 pages of this chapter but only these 3 videos ddid it for me and i could easy solve the questions except some memorizing. THANK YOU FOR THESE!!!
Always recommend this channel to my friends whenever they are stuck in either bio or phys or chem.

Very helpful thanks! keep making great videos :)
Amazing Amazing Amazinggggggg
God bless you!!
love these guys man
Great videos! Keep it up!
Amazing!!! love this

Do you have video on Liver too?
Does reabsorption occur in a dialysis machine?
No, the excess ions and waste is diffuse into the dialysis fluid filtering the blood and then returning it straight into the blood without the blood taking in more nutrients
yeah because of the concentration gradient, the dialysis fluid containing extra glucose and good stuff will diffuse into the blood stream so u don't lose any of the important stuff that u really need
@@nameless191 haha but then we would lose glucose particles since they're being filtrated too
4:55 i like the drawings 😂
Outro go brrrrrrrr
and all that biology!
Hey dont think you explained how the dialysis gets rid of urea , but I may be wrong
this may not be completely correct - there is no urea in the dialysis fluid which means there is a steep concentration gradient between the patient's blood containing urea and the fluid containing no urea. This allows for urea to diffuse across the partially permeable membrane from the blood into the fluid so there is no harmful urea left in the blood.
who else here from 11Y/Bi2
YOO
@@creyendo lol that was funnt to see
@@Seedboi say nothing
What exam board is it for?
@yoh7605 IGCSE
wait a minute but how does a dialysis machine manage the correct amount of water needed by the body to be reabsorbed since the machine is an external object and can't be controlled by ADH? How will we know what amount of water is needed to be reabsorbed by the patient if we can't use ADH?
This is such an interesting question damn. I'll look up on it and let u know!
the dialysis fluid contains the right amount of fluid that absorbs the contents of healthy blood, water ions, etc. So it it just removing excess water from the blood ensuring a right amount of water in the blood. It isn't reabsorbed I think, just water is diffused until it reaches its equilibrium
my teacher said that they have to do a blood test for the person and they see the concentrations and based on that they make the dialysis fluid
Gcse coming up
same. ready?
@@samfarr6239 nah, i tried though even with covid and that's what matters
Why can't they make an artificial kideny?
The dialysis treatment is basically an artificial kidney
