1
Q
What percentage of cardiac output do the kidneys receive?
A
20% (1L/min)
2
Q
What percentage of the blood is plasma?
A
55%
if normal hematocrit is 35-50%, plasma is 100-hematocrit
3
Q
What is normal RBF (renal blood flow) and normal RPF (renal plasma flow)
A
RBF = 1.1L/min RPF = 0.605L/min (.55*1.1)
4
Q
Normal GFR
A
0.125L/min (20% of plasma)
5
Q
What is the filtration fraction?
A
GFR/RPF
