Glomerular Filtration Quiz 1

1- Not filtered at the glomerulus
molecules about 10,000 daltons in size
water
plasma proteins
large ions


2- Extend from podocytes and wraps around endothelial cells
pedicels
basal lamina
filtration slits
all of the above


3- Kf NFP =
glomerular filtration rate
glomerular coefficient
glomerular hydrostatic pressure
capsular hydrostatic pressure


4- Calculate the net filtration rate fom the following values:
         blood colloidal pressure = 30 mmHg
         capsular hydrostatic pressure = 15 mmHg
         glomerular hydrostatic pressure = 55 mmHg

10 mmHg
40 mmHg
70 mmHg
100 mmHg


5- Juxtaglomerular cells
release a systemic vasoconstrictor
release a local vasodilator
release renin
