The dialysis solution has concentrations of things, like, vitamins/waste products such that the wastes from blood will diffuse into the solution and the vitamins etc. from the solution will diffuse into the blood. I think.

the dialysis fluid is the fluid which contains water, amino acids, gases, salts and glucose, it basically assists in the diffusion of appropriate substance to and in blood...i think...cause for people who have their kidneys failed...they cant reabosrb all the glucose and stuff that the body needs...
Similarities: They both remove nitrogenous wastes; they both maintain blood water and blood salt concentrationsdanz90 said:Isn't the HSC Advice Line closed atm? lol
Yess 2) is very important.. talking MHC molecules/markers is band 6 standard.Major Histocompatibility Complex - a protein molecule that is present on the membrane surface of all cells.. and presents antigens.
Can anyone give a rundown on Renal Dialysis, in comparison with normal kidney function? I know the basics...but need more detail
Do we have to be as specific as knowing what the role of dialysate solution is etc?
Differences: In the kidney, pressure filtration occurs, in dialysis diffusion occurs; the tubule is teh selectively permeable membrane in the kidney, the dialysis tubing is the the selectively permeable membrane in diaslysis; in the kidney both filtration and reabsorbtion occur, in dialysis on filtration occurs; the kidney works continually and is very efficient, while dialysis is intermittent.
The role of the dialysate solution is to maintain glucose, amino acid, water, mineral and vitamin concentration in the blood. Because there is no reabsorption, if it were not for the dialysate solution, these substances would diffuse out of the blood, however, by maintaining the same concentration in the solution as there is in the blood there is no gradient for diffusions (osmosis for water)
By remembering PMAT (Prophase, Metaphase, Anophase, Telephase) and watching these videos:danz90 said:

I've kind of got it.

thanks for that. there are some other good youtube videos that explain meiosis well: http://au.youtube.com/watch?v=D1_-mQS_FZ0dolbinau said:
my teacher said that remembering each phase is not necessary for our syllabus. we just need to know that in meiosis crossing over, random segragation and independent assortment occurs, and how this leads to variability in offspring.
