Renal Physiology — Flashcards

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

_____ is the major anion reabsorbed in the early PCT

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

Atrial natriuretic peptide causes vaso-_____ of afferent arterioles and, to a lesser extent, vaso-constriction of efferent arterioles

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

Juxtamedullary nephrons have _____ glomeruli (size) and thus higher GFR than superficial cortical nephrons

The _____ DCT is always impermeable to water (permeability)

In the cells of the proximal tubule, the enzyme _____ metabolizes glutamine to glutamate and NH4+

The primary regulation of aldosterone secretion occurs through changes in _____ (via the renin-angiotensin II-aldosterone system) and changes in serum potassium levels

Decreases in _____ (e.g. hemorrhage or decreased Na+) cause a decrease in renal perfusion pressure, which in turn increases secretion of the enzyme renin
