renal Flashcards
horseshoe kidney associated with
Turner’s syndrome
horseshoe kidneys get fixed low by
inferior mesenteric atrery
normal GFR
100 ml/min
nephrotic syndrome results in
albuminuria, hypoproteinemia, generalized edema, hyperlipidemia
normal filtration fraction
20%
location of juxtaglomular cells
efferent aterioles
effect of NSAIDS on aterioles
contrict (Prostoglandins dilate) afferent arteriole, increases RPF, GPR and FF stayes consistent (nsAid - Afferent)
Filtration fraction calulation
GFR/RPF
GFR estimated with
creatine clearance
RPF estimated with
PAH clearance
ACE inhibitors effect on arterioles
contstrict (Angiotensin II dilates) efferent arteriole, so RPF down, GFR up, so FF increases acE - Efferent)
plasma glucose level above which glocsuria begins
160mg/dL
plasma glucose level that saturates all glucose transporters
350 mg/dL
hartnup’s disease
deficnecy of neutral amino acid transporter (tryptophan), results in pellagra
reabsorbs all glucose and amino acids and most bicarb, Na, Cl, phophate and water
early PCT
PTH effect on early PCT
excretion of phosphate
Angiotension II effect on early PCT
increased Na, water, and bicarb absorption
part of nephron impermeable to sodium
thin decending loop
actively absorbes Na, K, Cl-
thick ascending loop
