reading physio kaplan... ADH chapter..
the last table, one column shows Primary Polydipsia ---
the book says
Permeability of collecting ducts to water goes DOWN
the video says
Permeability of collecting ducts to water goes UP (he's SAYING it goes down while pointing to an arrow that goes up!!!)
whats happening... ADH shud go down, coz u don wanna reabs even more water so then the permeability of collecting ducts shud go DOWN right???
is my kaplan wrong or my vid wrong?? AAARRRGGHH!!!
Thanks
Cheers!
Adrian

ur kaplan and ur video both are correct u know sometimes there cud be a slip of tongue if
u have already understood than just ignore the simple mistake which was not on purpose in
the video ...Primary polydipsia...ADH secretion goes down..cuz the patient drinks more and
pee more...and body cannot afford to reabsorb more cuz patient is drinking more..so
therefore ADH and permeability of collecting ducts to water shud go down.

hmm..In primary polydypsia the patient is taking in too much free water. This is supposed to dilute his plasma and it does. Now the kidneys ain't got a problem, so they will do their best to get rid of the extra water the patient is taking. For that mater, the body reduces ADH so that less water is re-absorbed in the collecting duct. We want to get rid of the extra free water right?. So permeability should go down letting the water to be excreted. The book is correct, the video might be wrong.
