1
Q
what is the Glomerular Filtration Rate (GFR)
A
amount of filltrate formed in all renal corpuuscles of both kidneys per minute
2
Q
what does too low of a GFR mean
A
sufficent waste products may not be removed from body
3
Q
myogenic mechanism is
A
a fast mechanism of autoregulation of GFR that increases blood pressure
4
Q
tubuloglomerular feedback is
A
a slow mechanism of autoregulation of GFR that prevents reabsorbtion of Na+ and cl- and inhibits the release of NO (a vasodialator)
5
Q
the rate of excretion =
A
GFR + rate of secretion - rate of reabsorbtion
6
Q
glomerular cappillaries is where
A
filtration of blood occurs
7
Q
pertubular cappilaries is where
A
vasa recta caeey away substances reabsorbed from filtrate
8
