This is for anatomy and physiology class, i dont understand, and i cant find the answer anywhere. Help would be super super appreciated.

Do you mean here? http://www.beltina.org/pics/glomerulus.jpg

I dont think so... my teacher is very confusing but i think since the chapter we are on is over Water, elcectrolyte, and acid-base balance...that she wants the chemical difference between each but i was thought filtrate was an action, so where the chemical....i dont know, im confused :(

ok, urine i heard can be defined as a super-filtrate of blood. yes, filtrate is the action of the blood passing through the glomerulus--bowman capsule and such. i think you will understnad better when you study the renal system, its not easy, but in few words its the long journey of the water extracted from the blood and the changes in electrolite composition, you know K, Na, Cl mainly.

ok well, i really appreciate your help. =D ive been doing questions for almost 9 hours now and by now my brains a little fried so THANKS!! Awesomeness. :)

the plasma travels through a system of vessels parallel to those of the circulatory system, there is a exchange of electrolites between the two as well as the elements of the immunitary system. To tell you the truth i dont remember the exact chemical composition of the different stages of this "filtrate" that will become urine. but i hope it helped you at least where to aim your shots. :-)

Glomerulus: Between the primary urine and the the bloodstream there are several layers of cells Lumen -> Fenestrated epitel -> Lamila basalis -> podocytes -> Primary urine. Diffusion between these is controlled by BP The Hydrostatic osmotic preasure in lumen -> Primary urine is 55mmhg The Blood colloid concentration gradient is 30mmg between Lumen -> primary urine, The osmotic preasure is the preasure of which the primary urine is transported further in the Nefron to Proximal tubuli. Proximal tubulis: 70% of all reabsorption of the nefron occursed here, Mg+, Cl-, Ca+, H2O, Aminoacids, Vitamines, Na+ Descending Helnes slynga: Epitel bound protein canals Aquaporin2 reabs a lot of H2O here through passive diffusion (Reglated by ADH) Ascending Helnes Slynga: lacks A2P channels therefore can't diffuse any H2O here. Distal tubuli: Last reabsorbation site inside the nefron before the primary urine exits into ductus bellini. Ca2+, Mg+, Na+, Cl-,K+ I've written a summary of what i consider is important to know about the Nefrone i believe the information you seek should be in there. Keep in mind that where ever there's reabsorption there is a bloodvessle and this could be refered to the electrolyte diffrence between urine & plasma aswell as filtration. But since theres no generalization of what is absorbed where i posted all the sites and what i can recall absorbs what.

I've written all of this of my notes, so there might come up terms which i've forgotten to translate from swedish. I'll make a readthrough and provide the correct terms.

Diffusion between these is controlled by BP The Hydrostatic osmotic preasure in lumen -> Primary urine is 55mmhg The Blood colloid concentration gradient is 30mmhg between Lumen -> primary urine, The osmotic preasure is the preasure of which the primary urine is transported further in the kidney to Proximal tubuli. Osmotic preasure is net diffrence between Hydrostatic osmotic preasure & Blood colloid concentration gradient. In this scenario 55-30 = 20mmhg Proximal tubulis: 70% of all reabsorption of the nefron occured here, Mg+, Cl-, Ca+, H2O, Aminoacids, Vitamines, Na+ Descending loop of Helne: Epitel bound protein canals Aquaporin2 reabsorbs a lot of H2O here through passive diffusion (Regulated by ADH) Ascending loop Helne: lacks A2P channels therefore can't diffuse any H2O here.

Most should be comprehendable now with accurate-"ish" corresponding english term. Forgot a few *Epitel - Epithelium *Nefrone - There is no english term for it, it seems. it's a active site between one Glomerulus to Ductus bellini. Substitute it with "Kidney" i suppose. Im sorry for the typos.
