Renal Physiology Flashcards
Hallmark of glomerular disease
proteinuria
ultimate site of filtration
renal corpuscle
effective filtration pressure
50 mmHg
one of the best predictors of a poor outcome in clinical DM
decrease in podocyte number
Dissolution or attenuation of mesangial matrix and degradation of MCs by apoptosis or lysis
mesangiolysis
cessation of nephroegenesis
36th week
glomerulogenesis
8-9th week
amount of blood filtered per day by the kidney
180 L
definitive mamallian kidney is from the
metanephros
kidney situated between
12th thoracic and 3rd lumbar
difference between inner and outer medulla
absence of Thick ascending limbs in the inner medulla
splitting and basket-weave lamellae of the GBM
Alport syndrome
mutations in Laminin B2
Pierson syndrome
inhibitor of the TAL transporter NKCC2
Furosemide
NCC is expressed in what segment
Distal tubule
majority of cell type in connecting segment
CNT tubule
majority of cells in the collecting duct
principal cells
most abundant cell type in the peritubular interstitium
type 1 fibroblasts
majority of renal innervation
efferent
decline in hydraulic pressure between the renal artery and the glomerular capillaries is greatest along the
afferent arteriole
ability of the arterial smooth muscle to contract and relax in response to increases and decreases in vascular wall tension
myogenic reflex
maintain a hypertonic inferstitial gradient
medulla
Intrinsic ability of the kidney to respond to perturbations that elicits a vasoactive response, which alters renal vascular resistance in the direction that maintain RBF and GFR
renal autoregulation
macula densa cells, extraglomerular mesangium and afferent and efferent arterioles of the glomerulus
juxtaglomerular apparatus
primarily responsible for mediating tubuloglomerular feedback
adenosine
humoral response
T helper cell 2 - antibody mediated
cellular response
T helper cell 1
steroid sensitive nephrotic syndrome
MCD
steroid resistant
FSGS
Ca dependent phosphatase which dephosphorylates nuclear factor of activated T cells
calcineurin
Na K ATPase
3 Na out 2 K in
Type of transport: Na K ATPase
primary active transport
Type of transport: a-KG cotransport
secondary active transport
type of transport OAT
tertiary active transport
