units of GFR
|
volume/time
|
|
normal GFR
|
180 L/day
125 ml/min |
|
GFR formula
|
Kf x NFP
|
|
formula for NFP
|
Pgc - (Pbc+ oncoticGC)
|
|
Kf increases when
|
increase in surface area due to relaxation of glomerular mesangial cells
|
|
Pgc increases when
|
increase in renal arterial pressure
increase in efferent arteriole resistance |
|
Pgc decreases when
|
increase in afferent arteriole resistance
|
|
Pbc increases when
|
obstruction of tubule
|
|
oncoticGC increases when
|
decrease in renal blood flow
|
|
filtration fraction formula
|
GFR/RPF
|
|
filtration fraction is greater at (high plasma flow / lower plasma flow)?
|
lower
|
|
what happens to GFR when only the efferent arteriole is constricted
|
first rises (Pgc affect dominates)
then falls (RPF affect dominates) |
|
what happens to GFR when only the afferent arteriole is constricted
|
falls (Pgc and RPF decrease)
|
|
what is tubuloglomerular feedback
|
regulation of GFR by the macula densa
|
|
RAAS affect on GFR and RPF
|
decrease in RPF with little change in GFR
|
|
ANP affect on GFR and RBF
|
increases both
