Flashcards in fong III Deck (18):
how much cardiac output is delivered to the nephron?
what occurs at the interface between vascular and epithelial structures?
is filtration highly or lowly selective?
what are the determinants of permeability across the glomerular filtration barrier?
amount filtrate/amount blood should =?
the filtration barrier carries what charge?
( - )
what selects for shape in during filtration?
endothelial cells and podocytes
what does SNGFR stand for?
single nephron glomerular filtration rate
what forces govern intravascular /transcellular fluid movements?
what pressure builds up as filtration proceeds?
capillary oncotic pressure
what are the regulators of glomerular filtration?
3. tuboglomerular feedback
what stimulates the renin-angiotensin-aldosterone system?
a drop in blood pressure
high tubular transport is measure by what?
macula densa cells
what are the units of clearance?
what are the units for filtered load?
t/f: your clearance will change as you change your concentration of inulin.
what is the solution to the impracticality of inulin infusion?
measuring creatinine clearance
