1
Q

What is the equation for urine excretion rate?

A

Urine excretion rate = urine concentration of a given substance x urine flow rate

(Excretion = (Ux) (V))

2
Q

What equation do we use to calculate GFR for molecules that meet our criteria?

A

GFR = (concentration of the substance in urine, x urine flow rate) / concentration of the substance in plasma

3
Q

What is the equation for filtered load?

A

Filtered load = plasma concentration x GFR

4
Q

What is the equation for urinary excretion?

A

Urinary excretion = amount filtered - amount reabsorbed + amount secreted

5
Q

What is the equation for the filtration fraction?

A

FF = GFR/RPF

(Filtration fraction = glomerular filtration rate / renal blood (plasma) flow)

6
Q

What is the equation for renal clearance?

A
7
Q

What is the equation for tubular reabsorption?

A

Tubular reabsorption = filtered load - urinary excretion + amount secreted
