Flashcards in Renal Deck (20):
1

what is osmolarity of blood?

280-300

2

where does ammonia and urea come from?

breakdown of amino acids

3

what is filtration?

using hydrostatic pressure to filter out selective solutes

4

what is a renal corpusle?

glomerulus + Bowman's capsule

5

which renal artery is shorter?

left

6

which is the longest renal vein?

left (has to cross over artery)

7

which one is the lower kidney?

right (liver is above it)

8

what is the hilum of the kidney?

where all arteries and veins enter the kidney

9

what is the renal capsule made of?

dense irregular CT

10

what is the renal fascia made of?

dense irregular CT-anchors kidney to wall

11

what is the point of the renal pyramids called?

renal papilla

12

what is the renal sinus?

where the hilum expands into a cavity

13

how much blood does the kidney receive?

25% of the cardiac output

14

what is the arterial renal pathway?

renal artery
segmental arteries
interlobar artery
arcuate artery
cortical radiate artery
glomerulus capillaries
efferent arterioles
peritubular capillaries

15

what is the venous renal pathway?

peritubular capillaries
cortical radiate vein
arcuate vein
interlobar vein

16

which glomerular capillary has the largest diameter?

afferent
creates a greater pressure gradient

17

what components should be in the filtrate?

glucose
electrolytes (sodium, potassium)
amino acids

18

what is a cortical nephron?

has a short loop of Henle
efferent arteriole supplies peritubular capillaries
most common nephron

19

what is a juxtamedullary nephron?

has a long loop of Henle
efferent arterioles supplies vasa recta (around loop, not peritubular capillaries)

20

whose job is it to retain water?

juxtamedullary nephrons
