Methamphetmine's diuretic properties

[tyrael]

I'm the same, I always like to know the fundamental mechanisms behind something.

Also something that relates to this that you might find interesting is the function of the nephrons of the kidney and how sodium and water are reabsorbed whilst potassium and chlorine are excreted; I've just started reading about this and how diuretics work to increase sodium excretion. There is a really cool diagram in the book that I might try and find online to post up.

I realise there are solbuiliy constants to "keep us in check" - on of these being Na/K [dont ask me what it is. lol]

I reckon you'll want to be looking at osmotic pressure/moliarty difficult (in the whole of the nephron but more specifically in the) the (decending) Loop Of Henle wher(afaika- obsorbs modt of the bofy "larger" eleytolytes amd such.

Regarding the fight-or-flight response; in general the digestive tract is slowed down during the release of catecholamines, I assume because blood flow is re-directed from it to skeletal muscle and vital organs. Apart from that there isn't much effect on urine output or sodium and potassium excretion as far as I'm aware.

That was my undertanding too. The release of the catecholamines - adrenaline/epinephrine, noradrenalinenorepinephrine and dopamine and
amoungst others), caused this reation. In fact, the digestive is one of the many organ reduces in fucntion/shut down during a fight or flight response.,
