Renal Physiology — Flashcards

[TF/P]x _____ 1 when the solute is reabsorbed less quickly than water

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

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

_____ 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+

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

_____ (Type 1) renal tubular acidosis is due to a defect in the ability of alpha-intercalated cells to secrete H+

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

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

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