Renal Physiology — Flashcards

_____ renal tubular acidosis is due to a defect in the ability of PCT cells to reabsorb HCO3-

In the proximal tubule cells, NH4+ is in equilibrium with _____ and H+

H+ secretion from -intercalated cells occurs via the luminal membrane _____ and H+-K+ ATPase pumps

Renin is responsible for the conversion of _____ to angiotensin I

The major action of ADH (vasopressin) is to increase _____ of the principal cells in the late distal convoluted tubule and collecting duct

H+ is secreted into the lumen of the early PCT via the _____ exchanger, where it combines with filtered HCO3-, forming H2CO3

In the _____ limb (loop of Henle), osmolarity of the interstitial fluid increases ("single effect")

The _____ limb (loop of Henle) is permeable to water

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

When CH2O is _____, urine is hypo-osmotic relative to plasma
