Renal Physiology — Flashcards

_____ clearance can be used to calculate effective renal plasma flow (eRPF) because it is both filtered and secreted

In the lumen of the collecting duct, _____ and H+ combine to form NH4+

Creatinine clearance slightly _____-estimates GFR because creatinine is moderately secreted by renal tubules

_____ is the major anion reabsorbed in the early PCT

The _____ of the glomerular filtration barrier contains heparan sulfate, which acts as a negative charge barrier

If the filtered load is _____ than the excretion rate, there has been net secretion (reabsorption or secretion)

The H2CO3 formed inside the cells of the PCT dissociates into _____ and HCO3-

In the _____ of ADH, free-water clearance (CH2O) is positive

In the _____, 70% of the filtered urea is reabsorbed via facilitated diffusion (if ADH is present)

HCO3- is transported across the basolateral membrane into the blood by:\n1. Proximal tubule: _____\n2. Alpha-intercalated cells: Cl--HCO3- exchange
