Glomerular filtration — Flashcards

Are small, charged solutes (e.g. Na+, K+, Cl-) affected by the negatively charged glomerular filtration barrier? _____

If Cx _____ GFR, there is no net secretion or reabsorption of X

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

Inulin clearance can be used to calculate _____ because it is freely filtered and is not reabsorbed or secreted

What effect does afferent arteriolar constriction have on RPF? _____

What effect does afferent arteriolar constriction have on filtration fraction? _____

Juxtamedullary nephrons have _____ glomeruli and thus _____ GFR than superficial cortical nephrons

Hint: size

What effect does constriction of the ureter have on GFR? _____

What effect does increased plasma protein concentration (πGC) have on RPF? _____

What effect does decreased plasma protein concentration (πGC) have on filtration fraction? _____
