urinary system Flashcards
1
Q
reuptake of Na ions
A
aldosterone
angiotensin
renin
2
Q
repute of water
A
ADH antidiuretic hormone
3
Q
flush Na, flush water, low blood pressure and inhibit vasoconstriction
A
ANP atrial natriuretic peptide, ended on page 1000
4
Q
Three things about glomerular capillaries that contribute to glomerular filtration rate:
A
surface area
fenestrations
blood pressure + small efferent arteriole
5
Q
normal gfr
A
120-125 ml.min
6
Q
how does tubuloglomerular feedback work?
A
macula densa senses NaCl bc too much, too high GFR can’t keep up with reabsorption of Na
vasoconstriction which lowers GFR to normal rate
7
Q
water leaves the descending or ascending loop of henle?
A
descending
8
Q
solutes reabsorbed in ascending or descending limb?
A
ascending
