0

possible cause of glucose in urine

tubular dysfunction
glucose overflow

1

what is the kidney glucose threshold

160mg/dL

2

protein in urine is called

proteinuria

3

how does the kidney help in BP regulation

renin angiotensis system

4

organs involved in RAS

kidney
lungs

5

criteria for good substance for clearance test

freely passes glomerulus

neither abosorbed nor secreted bu the tubules

6

formula for clearance

conc of subs in urine over conc of subs in plasma times 1.73

expressed in milliliters per minute

7

urine sample used for clearance test

24-hour urine

8

what are the bodily fluids aside from urine, tears, saliva

CSF
synovial
seminal
amniotic
serous
gastric
sputum
sweat
feces

9

which fluid is used to diagnose meningitis

CSF

10

which fluid is used to diagnose arthritis

synovial

11

which fluid is used to diagnose inborne diseases

which fluid is used to diagnose

12

when are inborn diseases usually checked

1st and 3rd trimester

13

which fluid is used to rule out malignancies

serous fluid

14

which fluid is used to diagnose ulcer, etc

gastric

15

which fluid is used to diagnose cystic fibrosis

sweat

16

which is an early sign of colon cancer

FOBT (fecal occult blood test)

17

CSF is used to diagnose

meningitis

18

synovial fluid is used to diagnose

arthritis

19

seminal fluid is used for

fertility test
medicolegal purposes

20

amniotic fluid is used to diagnose

inborn diseases

21

sputum is used to diagnose

TB

22

which fluid is used to diagnose TB

sputum

23

sweat is used to diagnose

cystic fibrosis

24

this is the waste product from blood filtration by kidney

urine

25

major organ of urine formation

kidney

26

location of kidney

retroperitoneal space

27

basic units of the kidney

nephron

28

number of nephrons per kidney

1-1.5 million

29

percent of blood that enters the kidney per minute

20%

30

the type of arteriole where blood enters the kidney

afferent arteriole

31

the type of arteriol where blood exits the kidney

efferent arteriole

32

amount of blood in kidney after filtration

1200mL -> 120mL

33

arteries in kidney

renal arteries

34

other function of kidney aside from filtration

acid base regulation
plasma and electrolytes regulation
EPO production
BP regulation

35

what stimulates the kidney to produce EPO

hypoxia

36

PCT stands for

proximal convoluted tubules

37

the site of active reabsorption of threshold substances

PCT proximal convoluted tubules

38

DLH stands for

descending limb of Henle

39

site of active reabsorption of water and electrolytes

DLH descending limb of Henle

40

site of urine concentration

DLH descending limb of Henle

41

why is urine concentrated in the DLH

water is reabsorbed, making it more concentrated

42

what is reabsorbed in the PCT

threshold substances

43

what is reabsorbed in the DLH

water and electrolytes

44

the site where there is no water reabsorption

ALH ascending limb of Henle

45

why is there no water reabsorption in the ALH

it is impermeable to water

46

it is the usual site of urine crystal and casts formation

ALH ascending limb of Henle

47

ALH stands for

ascending limb of Henle

48

example of a diuretic

thiazide
osmotic
k-sparing

49

hormones in kidney

parathryroid hormone
aldosterone

50

DCT stands for

distal convoluted tubules

51

site of secretion of ammonia etc

DCT distal convoluted tubules

52

site where reabsorption is continued

DCT distal convoluted tubules

53

processes in urine formation

glomerular filtration
tubular reabsorption
tubular secretion

54

importance of urinalysis

diseases or infection diagnosis
metabolic disorder diagnosis not related to kidney
to monitor course of treatment
pregnancy test
drug abuse checking

55

function of KFT

glomerular and tubular competency

56

this test is for filtering capacity if golmerulus

creatinine clearance
