Here are the key steps to calculate the excretion rate of a substance:1. Measure the urine volume per minute (ml/min)2. Measure the concentration of the substance in the urine (mg/ml or mmol/l) 3. Multiply the urine volume by the concentration of the substance in urine:Excretion rate = Urine volume (ml/min) x Concentration of substance in urine (mg/ml or mmol/l)For example, if the urine volume is 100 ml/min and the glucose concentration in urine is 50 mg/ml, then:Excretion rate of glucose = 100 ml/min x 50 mg/ml = 5,000 mg

27. • Urine formation:
The rates at which different substances are excreted in the urine
represent the sum of the three renal processes. (L/day)
• The three renal processes:
1) glomerular filtration.
2) reabsorption of substances from the renal tubules into the blood.
3) secretion of substances from the blood into the renal tubules.
Excretion = Glomerular Filtration – Tubular absorption + Tubular secretion
Excretion = G.F – T.A + T.S
28. Calculation of net filtration pressure:
(Glomerular hydrostatic P. + Bowman's oncotic P.) – (Bowman's hydrostatic P. + Glomerular oncotic P)
Net filtration pressure = (G.H.P + B.O.P) – (B.H.P + G.O.P)
Net filtration pressure = (G.H.P + B.O.P) – (B.H.P + G.O.P)
= (60 + zero) – (32 + 18)
= 10 mm Hg.
29. Measurement of GFR:
It is measured by the use of Inulin or creatinine clearance.
Clearance of a substance is :
the volume of plasma cleared from that substance / minute.
U (x) × V
C (x) = ------------------- = ( ml / min )
P ( x )
U ( x ) = concentration of substance x in urine ( mg /ml ).
V = urine flow rate ( ml / min )
P ( x ) = concentration of substance x in plasma (mg / ml )
30. •Calculation of Filtration fraction:
It is the percentage ratio of renal plasma flow (RPF) that becomes
filtrated (OR) it is the percentage ratio of GFR to RPF.
= GFR ÷ RPF = 125 ÷ 650 = about 20 %
31. • Calculation of Filtered load of a substance:
= GFR x concentration of substance in plasma
Q) If glucose concentration in blood is 100 mgm% (1 mgm/ml) and
GFR = 125 ml/min, Filtered load of glucose = 125 x 1 = 125
mgm/min. Calculation of Excretion rate of a substance ?
= (urine volume/min) x (concentration of substance in urine)
