===Potassium and Aldosterone===

* [[Aldosterone]] is the most important regulator of potassium

* [[Important Hormonal Regulators of the Kidney - Anatomy & Physiology#Potassium|Aldosterone]] is the most important regulator of potassium

* It causes increased secretion of potassium

* It causes increased secretion of potassium

* Increased potassium directly stimulates [[Aldosterone]] secretion

* Increased potassium directly stimulates [[Important Hormonal Regulators of the Kidney - Anatomy & Physiology#Potassium|Aldosterone]] secretion

* Increases the activity and number of Na⁺ / K⁺ ATPase in basolateral membranes of the principal cells in the collecting duct and distal tubule

* Increases the activity and number of Na⁺ / K⁺ ATPase in basolateral membranes of the principal cells in the collecting duct and distal tubule

* Potassium moves into the cells and is then excreted down an electro-chemical gradient
