kidney

Question 1

arteries of the kidney

Answer 1

cortical radiate
arcuate
interlobar
segmental
renal

Question 2

arterioles of the nephron

Answer 2

afferent enters glomerulus
efferent leaves

peritubular capilaries
vasa recta

Question 3

Na+ from PCT lumen into PCT epithelial cell

Answer 3

co-transport with glucose

Question 4

na+ from PCT epithelial cell into capillary

Answer 4

anti-port with K+

Question 5

osmolarity of LoH

Answer 5

300 in PCT
1200 at bottom of LoH
100 Thick ascending limb

Question 6

low vitamin D

Answer 6

weak bones

Question 7

features of juxtamedullary nephron

Answer 7

renal corpuscle close to medulla
long loop of henle
vasa recta down LoH

Question 8

effect of LoH size on urine

Answer 8

longer loop of henle = more concentrated urine

more water is reabsorbed

Question 9

features of cortical nephron

Answer 9

85% of nephrons are cortical
almost entirely in cortex
no vasa recta

Question 10

role of zona occludens

Answer 10

tight junctions

make tubules impermeable to water

Question 11

what do loop diuretics target

Answer 11

K+/Cl-/Na+ pump of thick ascending limb

Question 12

role of SGLUT2 in kidney

Answer 12

co-transport/symport of glucose and sodium into PCT epithelial cell from PCT lumen

Question 13

role of thiazides

Answer 13

decrease blood volume

cause renin secretion

Question 14

where are V2 receptors found

Answer 14

basolateral cell membranes of principle cells

collecting duct
