TY - CHAP M1 - Book, Section TI - Regulation of Potassium Balance A1 - Eaton, Douglas C. A1 - Pooler, John P. Y1 - 2018 N1 - T2 - Vander’s Renal Physiology, 9e AB - State the normal balance and distribution of potassium between cells and extracellular fluid.Describe how potassium moves between cells and the extracellular fluid, and how, on a short-term basis, the movement protects the extracellular fluid from large changes in potassium concentration.State why plasma levels of potassium do not always reflect the status of total-body potassium.State how insulin and epinephrine influence the cellular uptake of potassium and identify the situations in which these hormonal influences are most important.State the relative amounts of potassium reabsorbed by the proximal tubule and thick ascending limb of Henle’s loop regardless of the state of potassium intake.Describe how nephron segments beyond the thick ascending limb can manifest net secretion or reabsorption; describe the role of principal cells and intercalated cells in these processes.List inputs that control the rate of potassium secretion by the distal nephron.Describe the actions of ROMK and BK potassium channels in conditions of low, normal, and high potassium excretion.Describe how changes in plasma potassium influence aldosterone secretion.State the effects of most diuretic drugs on potassium excretion.
