clearance Flashcards
1
Q
if a substance is freely filtered and completely secreted into the nephron, what is the clearance equal to
A
renal plasma flow
i.e. all PAH enters the tubule and none is left in the renal vein
2
Q
how can you calculate renal blood flow from renal plasma flow
A
53% is plasma
RPF x 100/53
3
Q
how do you calculate clearance
A
urine concentration x urine flow rate / plasma concentration
4
Q
the clearance of glucose is 0. what does this mean
A
it is completely reabsorbed
5
Q
the clearance of inulin is 125 what does this mean
A
it is neither reabsorbed or secreted
6
Q

A
it is completely secreted and no reabsorption
