The K<sup>+</sup> in the ECF only represents a very small amount of the total K<sup>+</sup> in the body; however its concentration is maintained within very strict parameters.  The homeostasis of K<sup>+</sup> is managed by three routes:

#Cellular translocation

#Cellular translocation - this is the main method of control; it is an acute response that triggers Potassium movement either into or out of the cells.  
This is the main method of control; it is an acute response that triggers Potassium movement either into or out of the cells.

#Renal excretion - this method makes up 90% of the chronic response (takes 4-6 hours to respond). It allows fine control and is regulated by [[Aldosterone|Aldosterone]]
#Renal excretion

#GI excretion - this route makes up the other 10% of the chronic response and becomes significant in cases of renal failure. This response is also influenced by [[Aldosterone]].
