Q
What is the equation for GFR
A
GFR=Ui x V /Pi
1
Q
Why measure glomerular filtration rate?
A
Estimate of how efficiently the kidneys are working, shows severity of kidney disease and used to dictate how much of certain drugs can be prescribed.
2
Q
Factors effecting filtration rate.
A
Capillary hydrostatic pressure, direct to GFR
Colloid osmotic pressure, inverse to GFR
Bowmans space pressure, inverse to GFR
3
Q
Layers of glomerular filter
A
Capillary endothelial cells, fenestrated
Basement membrane, negatively charged glycoproteins repel anionic proteins
Podocytes, slit pores
