Kidney Rate calculations Flashcards
how is the rate of filtration of a substance calculated
= [substance] in plasma x GFR
how is the rate of excretion of a substance calculated
= [substance] in urine x urine flow rate(Vu)
when can we say that net reabsorption of a substance has occurred
when rate of filtration > rate of elimination
how is the rate of reabsorption calculated
= rate of filtration - rate of elimination
when can we say that net secretion of a substance has occurred
when rate of elimination > rate of filtration
how is rate of secretion calculated
= rate of elimination - rate of filtration
what do the rates of reabsorption and secretion reflect in terms of kidney function
they reflect the tubular modification of the substance
