how much potassium goes through the kidney in a day
where is most potassium found
how much potassium is excreted in urine
where do you get potassium from
how much potassium is found in ecf
how much potassium is found in icf
why is most k found in icf`
how does cell interior stay negative? why does this happen?
what determines cell transmembrane potential gradient? what does this mean?
why is resting membrane potential important?
how does the b2 catecholamine receptor promote cell k uptake? describe this process
how does insulin promote cell k uptake?
what are two methods for k uptake?
how does metabolic acidosis impact k balance? pathway explain
why does hypokalemia occur
why does hyperkalemia occur
when is the cell hyperpolarized
when is the cell hypopolarized
what happens to muscles and heart rate with hypokalemia
what happens to muscle and heart with hyperkalemia
why can hyperkalemia lead to asystole

where is all of the potassium in urine secreted
what is the transport protein in the CD
what k channels are in the CD
what lets k be secreted in the CD
where is the principal cell? how is k secreted in ?
where is the intercalated cell? how does is lead to k secretion?
how does sodium delivery regulate potassium secretion>
how do tubule flow rates regulate k secretion?
how does lumen negativity regulate k secretion?
how does aldosterone regulate k secretion?
what stimulates vs inhibits aldosterone? why?
how does aldosterone lead to k secretion
what does aldosterone do to the collecting duct
what happens in a state of low ecf volume? why?
what happens in a state of ecf expansion? why?
what is the pathway to excrete potassium after youve eaten
how is potassium excreted when you are fasting
