renal physiology Flashcards
kideny function
homeostatic regulation of water and ion content of blood
excrete metabolic waste product
produce hormones
interior of kidney has 2 layers
outer cortex
inner medula
how are the layers formed
use neurons
80% of neurons are
cortical
20% of neurons are
juxtamedullary
what makes up the renal corpuscle
Bowman and glomerus
from bowman the filtered flid will go to
proximal tubule
from the proximal tubule it will go down
loop of henle
vascular supply to the nephron
blood flows from …… arteriole to glomerulus and leaves into ………… and then ……. capillaries
afferent
efferent
peritubular
what are long peritubular capillaries which dip into medulla are called
vasa recta
renal capillaries join to form
venules
fluids are …… from ………. back to blood at ………… capillaries
reabsorbed
tubule
peritubular
autoregulation of GFR
- myogenic mechnism of regulation
second part of autoregulation of GFR
2.Tubuloglomrular feedback
clearance:
urine conc x urine flow rate/ plasma concentration
