Flashcards in Ch 26 Lec 1 - Urinary System Deck (72):
1

urinary organ produces urine

kidney

2

urinary organ that takes urine to bladder

ureter

3

kidney is covered by these three things

renal capsule, renal fascia, perinephric adipose

4

superficial structure of kidney that is penetrated by renal artery, vein, and ureter penetrate

hilus

5

two layers of kidney

renal medulla, renal cortex

6

outer granular layer of kidney

renal cortex

7

renal papilla of renal pyramids empties into blank

minor calyces

8

minor calyx empties into blank

major calyces

9

major calyces empties into blank

renal pelvis

10

renal pelvis turns into blank

ureter

11

after going into glomerulus, blood in kidneys go to blank, then blank, then blank

efferent arterioles, peritubular capillaries, venules

12

functional unit of the kidney and there are blank per kidney

nephron, 1 million

13

nephrons are not blank if damages

replaced

14

amount of functional nephron essential for survival

1/3

15

two regions of nephron

renal corpuscle, renal tubule

16

renal corpuscle is made of blank and blank

glomerulus and bowman's capsule

17

cluster of capillaries off afferent arteriole

glomerulus

18

glomerulus has blank endothelium on capillaries

fenestrated

19

two layers of renal corpuscle

visceral, parietal

20

part of visceral layer that adheres to the glomerulus

podocytes

21

podocytes are highly blank cells

branched

22

branches of podocytes are called blank

pedicels

23

outer wall of renal glomerular capsule

parietal layer

24

the filtration of blood is aka blank

glomerular filtration

25

plasma becomes blank in the capsule

filtrate

26

continues from renal corpuscle

proximal convoluted tubule

27

proximal convoluted tubule is made of blank epithelium with a brush border

cuboidal

28

proximal convoluted tubule absorbs blank percent of filtrate

80

29

proximal convoluted tubule only filters out blank nutrients and blank percent of essential ions

organic, 60

30

this has a descending and ascending limb

loop of henle

31

limb of loop of henle that is thin

descending

32

limb of loop of henle that is thick

ascending

33

renal tubule that is close to renal corpuscle

distal convoluted tubule

34

distal convoluted tubule is for blank and blank

reabsorption, secretion

35

blank is reabsorbed due to blank in distal convoluted tubule

Na+, aldosterone

36

water is reabsorbed due to blank in distal convoluted tubule

ADH

37

distal convoluted tubule secretes blank and blank

H+, K+

38

distal convoluted tubule drains into blank tubules then collecting blank

collecting, ducts

39

collecting ducts go to blank ducts then blank then blank then blank then blank

papillary, minor calyces, major calyces, renal pelvis, ureter

40

final water adjustments are made in the blank and blank

distal convoluted tubule, collecting ducts

41

if permeability of collecting system is low then there are blank amounts of blank urine and less blank presence

large, dilute, adh

42

if permeability of collecting system is high then there are blank amounts of blank urine and more blank presence

smaller, concentrated, adh

43

specialized cells that monitor ion concentration of distal convoluted tubule filtrate

macula densa

44

juxtaglomerular complex is made of these two thigns

distal convoluted tubule, afferent arteriole

45

these cells are in the afferent arteriole and are smooth muscle cells in arteriole wall

juxtaglomerular cells

46

in the juxtaglomerular complex, when Na+ and Cl- is low then blank secretes blank

macula densa, renin

47

these constrict the afferent arteriole to increase filtrate

juxtaglomerular cells

48

two types of nephrons

cortical, juxtamedullary

49

short nephron mainly in cortex and produces standard blank

cortical, urine

50

nephron where corpuscles are in medulla and produces blank urine

juxtamedullary, concentrated

51

glomerulus filters out blank liters per day of filtrate

180

52

blank percent of water is reabsorbed and blank percent of filtrate enters renal pelvis

99, 1-5%

53

four hormones that affect urine concentration

pth, aldosteroone, renin, adh

54

hormone that increases calcium reabsorption

pth

55

hormone that increases Na reabsorption and K excretion

aldosterone

56

hormone that increases filtrate concentration

renin

57

hormone that increases water reabsorption in distal convoluted tubule and collecting duct

adh

58

ureters are lined with blank

mucous membranes

59

urine can blank but not leave through the opening flap of bladder

enter, leave

60

hollow muscular sac that is behind the pubic symphis

bladder

61

bladder is made of blank fibers, blank muscles and many blank when empty

elastic, involuntary, rugae

62

in men the bladder is superior to blank

prostate

63

in women, bladd is inferior to blank

uterus

64

area at base of bladder bounded by openings of ureter and urethra

trigone

65

these glands secrete mucous in urethra

urethral

66

female urethra is blank than males

shorter

67

release that is controlled by two sphincters and both sphincters must be open to urinate

micturition

68

two sphincters of micturition

internal urethral, external urethral

69

micturition sphincter that is involuntary

internal urethral

70

micturition sphincter that is voluntary

external urethral

71

loss of urine without voluntary control

incontinence

72

micturition is the combination of blank and blank

reflex, urination
