Potassium Regulation — Flashcards

The _____ cells of the late distal tubule and collecting duct secrete H+

Some _____ in the cells of the thick ascending limb diffuse back into the lumen, creating a lumen positive potential difference

In the presence of _____, aquaporin 2 channels are inserted in the luminal membrane of principal cells of the late distal tubule and collecting duct

The major solutes absorbed in the proximal tubule are _____ and NaHCO3

Reabsorption of Na+ in the collecting duct creates a _____ luminal potential that facilitates K+ excretion

Mineralocorticoids (aldosterone) cause increased renal _____ secretion via action on the -intercalated cells of the late distal tubule and collecting duct

The _____ cells of the late distal tubule and collecting duct secrete K+

What formula is used to calculate clearance? _____
