Flashcards in Lecture 28: Embryology/Anatomy, Microstructures of the Kidney Deck (20):
1

kidneys function

filter blood, produce urine

2

how much fluid is filtered daily

180 liters

3

how much urine produced daily

1-2 liters

4

how kidneys do job

remove metabolic waste products, foreign substances, drugs; regulate volume and composition of water and electrolytes in extracellular fluid; control acid-base balance; renin synthesis; erythropoietin synthesis; vitamin D conversion; gluconeogenesis

5

kidney's endocrine functions?

renin synthesis- regulate arterial blood pressure, erthrypoietin synthesis- stimulate erythrocyte production in bone marrow

6

important internal structures of kidney

cortext, medulla, papilla, calyces

7

nephron/its parts

functional unit of the kidney; renal corpuscle, proximal convoluted tubule, loop of Henle, distal convoluted tubule

8

how many nephrons in a kidney

1 million

9

renal corpuscle components

bowman's capcule + glomerulus

10

bowman's capsule components

parietal layer, visceral layer, bowman's space

11

podocytes components

visceral layer of bowman's capsule

12

glomerulus components

tuft of capillaries supported by mesangium

13

loop of henle components

thick descending limb + thin limbs + thick ascending limb

14

renal circulation path

renal artery > afferent arteriole > capillaries > efferent arteriole > capillaries surrounding tubules OR vasa cecta around loop of Henle in medulla > renal vein

15

filtration slit

important structure of podocytes

16

functions of podocyte cytoplasm

contractile, phagocytic; produce glomerular basement membrane

17

the 3 components of the filtration barrier

???

18

mesangium

interstitial tissue between glomerular capillaries

19

mesangial cell functions

matrix production- support glomerular cap, contractile- impact filtration, vasoactive, phagocytic- immune, proliferative- in glomerular disease

20

differences between proximal and distal tubules
