contraction of efferent
macula densa cell will when conc of the
produce prostaglandin
send the single to the juxaglomercula cell to release renin
where does the urea coming from
AA metabolism
is urea level a sensitie marker compared to creatinine ? Y / N
N
where does the creatinine coming from
mususcle metabolism
higher Scr indicates good or bad kidney function ?
bad
creatinine goes through
filtration and secretion
should we only look at creatinine level T/F
F
calculation for CC
(140-age) x weight / 0.815 x Scr
female x 0.85
ideal body weight
