On Alan's notes he has that ADH increases the permeability of the distal convoluted tubule to H2O. Isen't it the collecting duct's permeability that increases to H2O?

 

[jefff]

i believe its both distal convoluted tubule and collecting ducts via aquaporins

Alright, thanks.

So "jefff"...I feel stupid because I actually thought that was a bug on my screen lol that little animated bug you got going on really fooled me, I had to laugh at myself because I actually got a napkin to catch it lol

Lmao oh man that thing does look real. Creeped me out for a sec.

ADH/Vasopressin/Aldosterone all pretty much do the same thing, which is increase water uptake, increasing blood volume, increasing blood pressure.

im glad you guys got a kick out of it, lol @ the napkin

and yep 2pac is right

more specifically adh controlled by baroreceptors and osmoreceptors in the brain
---increased secretion for low bp and high osmolality respectively

and aldosterone is controlled by the renin-angiotensin system (specifically angiotensin 2), low [na+] detected by the macula densa of the kidney starts the RAS
---aldosterone causes na+ reabsorption (water follows) and k+ excretion
