Q
Name some parts of the extracellular compartment
A
CSF, GI fluid, ocular fluids, vasculature/plasma
2
Q
Name some components of the intracellular compartment
A
Red blood cells
3
Q
Where is ADH made?
A
Cells in the supraoptic nucleus
4
Q
Where is ADH stored
A
Posterior pituitary
5
Q
What causes ADH release
A
Plasma osmolality (increase)
Blood volume (decrease)- causes greater amount of ADH
6
Q
What is the mechanism of action for ADH
A
Binds to peritubular side of collecting duct, activates adenylate cyclase, which inserts aquaporins on apical side of collecting duct
