Glomerulus Filtration Flashcards
Glomerulus Filtration
fluid that enters capsular space
forms filtration membrane
Podocytes + glomerular capillaries
Filtration membrane permits what to pass
water
small solutes
Filtration membrane prevents what from passing
blood cells
platelets
substances filtered from the blood crosses these three filtration barriers
glomerular endothelial cell
basal lamina
filtration slit
why are glomerular endothelial cells so leaky
fenestrations
what extends from each podocyte
pedicels
pedicels
footlike projections that wrap around glomerular capillaries
the spaces between pedicels
filtration slits
thin membrane that extends across filtration slit
slit membrane
function of slit membrane
allows passages of small molecules
Filtration
the use of pressure to force fluids and solutes through a membrane
why is fluid filtration in renal corpuscle much larger than any other capillaries of the body
larger surface area for filtration
filtration membrane is thin and porous
BP is much higher in glomerulus capillaries
