it is the collecting ducts.as inulin is only filtered not reabsorbed.

exactly tht's why i said loop of henle!
let's assume tht pt's hydration status is good and he if forming dilute urine ....!!!!!!!!!!!!!
the osmolarity change tht occur from the tip of loop of henle till the DCT is not affected by hydration status!

anybody gone through the similar q in BRS.
it is on page 208 q.no.38.it asks about inulin max.conc.during antidiuresis.water is reabsorbed along the entire nephron(except ALH& cortical diluting segment),the inulin conc.increases.
the book mentions that inulin conc.depends on water reabsorption,increases with it.??i myself am not clear with this.
ssrpk did ur answer match with any book :?:

hey man don't get confused u are ofcorse right!
i am just saying tht if they do mention abt ANTIDIURESIS then tht means the conc. of inulin will increase in the collecting ducts....however if there is marked diuresis then inulin will not get too concentrated!
i mentioned abt tip of loop of henle coz in the q here it's not mentioend abt antidiuresis!

Can any good doc explain to me what the "tip of the loop of Henle is"?
Its just that its a VERY detailed science.
My answer would be collecting duct..

Thanks ssrpk.i think i had gone nuts not able to get into my own answer.
the tip of loop of henle is portion where the descending takes a u turn to become ascending.and since the ascending is impermeable to water it will not conentrate inulin on contrary it will dilute it.
