In high potassium serum levels, kidney compensation occurs by?
Ans. is'c'i.e., Increased secretion in DCT[Ref: 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.
Decreased reabsorption in PCT
