<prompt> In high potassium serum levels, kidney compensation occurs by?Decreased reabsorption in PCTIncreased secretion in PCTIncreased secretion in DCTDecreased reabsorption in loop of Henle  <response>: Ans. isci.e., Increased secretion in DCTRef: Guyton hall p. 201Potassium transpo:Potassium is one of the few substances that are both reabsorbed as well as secreted by the renal tubules.The reabsorption of about two-thirds of the filtered K occurs in the proximal tubulesK reabsorption as weII as secretion takes place.Here also, reabsorption of K occurs independent of K status of the body.It is the secretory process that K regulated by aldosterone in response to the K and Na status of body.
