Regulate pH, production of erythropoietin which stimulates rbc production (regulates o2 capacity) vitamin D turned to active form. 120ml/min filtered. only 1ml/min of urine.

what are mesangial cells?
from immune system, ingest matter that may leak out fro,m any damage part of capillary vessel.
2 of 11
What type of cells line bowman's capsule?
Parietal cells.
3 of 11
filtration
through fenestrate endothelial cells. proteins -ve charged so can't pass through barrier.
4 of 11
podocytes
wrap around capillary and endothelial cells. small processes called pediciles, gaps between are filtration slits.

What happens in PCT?
75% reabsorbed. cells have brush boarder. actively tranpsorted so lots of M. cells are collumnar
6 of 11
Loop OH
function is water recovery. Thin D-flatterened cells ThickA-cuboidal cells
7 of 11
DCT
reabsorption of Na ions control by aldosterone hormone. paler than PCT and more cuboidal cells
8 of 11
Juxtaglomerular apparatus
when DCT come in to contact with arteriole cells become longer-called macula densa. JG cells (sm cells) produce renin.
9 of 11
Collecting tubule/duct
tubule-absorbed Na and secretes K+. have intercalated cells that balance pH. CD-columnar cells.
10 of 11
The ureter
connective tissue and two layers of muscle.
