kidney ;urine

Question 3

buffer for H

Answer 3

bicarb

Question 4

resp acidosis

Answer 4

accum of CO2 which makes H

Question 5

any problem with ventilation

Answer 5

inc CO2

Question 6

diabetics and hypoxia

Answer 6

produce acid

Question 7

normal diet

Answer 7

make diet

Question 8

net exogenous acid production

Answer 8

acid made from protein digestion and diabetes and hypoxia

Question 9

tf amt of acid in body is less than ingest per day

Answer 9

true

Question 10

tf most of bicarb reabsorption occurs in prox tubule an none goes into urine

Answer 10

t

Question 11

tf bicarb is reabsorbed at all parts of renal tubule

Answer 11

t

Question 12

at the prox tubule — bicarb is reabs and — h+ is secreter

Answer 12

1;1

Question 13

prox tubule luminal mebrane how do you get H+ out into lumen

Answer 13

thru exchanger(with NA) and pumP

Question 14

how does HCO3 get to cap at basolat membrane of Prox tubule

Answer 14

cotransport with NA

exchange with Cl

Question 15

tf in prox tubule and collecting duct

h secreted and HCO3 reabsorbed

Answer 15

t

and both 1;1

Question 16

at luminal side of the collecting duct

H get secreted by

Answer 16

pump with H+

and exchange with K(need ATP)

Question 17

how does hco3 get to cap side in CD

Answer 17

exchange with CL

Question 18

intercalated alpha type cell occurs

Answer 18

at CD to resorb bicarb

Question 19

principal cells have wat features

Answer 19

aqp2 and Na channel

located in CD

Question 20

interacalated cells

Answer 20

H pump

Question 21

beta intercalated types cells are used to

Answer 21

transfer hco3 to tube in alkalosis(excess hco3 in blood)

Question 22

purpose of interacalated alpha; vs beta cells

Answer 22

reabsorb bicarc; secrete bicarb

Question 23

in intercalated beta cells of the cd

hco3 secreted in eaxchanged for

Answer 23

• CL

Question 24

reabs H+ and secretion of Bicarb occurs in

interacalate alpha

intercalated beta

prox tubule

Answer 24

intercalated beta

Question 25

exhange of h with urinary buffer

Answer 25

h+ with atp pump

bicarb exchange for CL

Question 26

tf ammonium production and bicarb reabsorption are 1;1 in the proximla tubule

(h excretion from urine)

Answer 26

T

Question 27

NH4 reabsorbs —–

and get resecreted as —–

Answer 27

at thick ascending limb

nh3 in the collecting duct

Question 28

contributes to 2/3 of acid excretion from urine

Answer 28

ammonium production

Question 29

tf ammonium production to excrete acids in urine is ridge and take up 2/3 of total acid excretion in urine

Answer 29

f

flexible

2/3 correct

Question 30

during ammonium formation to excrete acid in urine

glut braks down to bicarb and nh4(1;1)

nh4 dissolves away to tubular fluid alone

nh3 is exchanged for na on the tub. membrane

Answer 30

glut braks down to bicarb and nh4(1;1)

Question 31

renal failure

Answer 31

patient cant get rid of acid

Question 32

diabetic acidosis

Answer 32

inc nh4 and ta in cap

Question 33

acidosis

Answer 33

inc in acid in tubular cells

Question 34

what does acidosis trigger

Answer 34

transporter and enzyme secretion to transport acids(nh4 and TA) to urine

Question 35

excersizing

Answer 35

met. acidosis

Question 36

diahrreha

Answer 36

met. acidosis

Question 37

vomit

Answer 37

met. alkalosis

Question 38

trigger hypervent

Answer 38

met acid.

Question 39

trigger hypovent

Answer 39

met. alk.

Question 40

tf metabolic acidosis results in low ph and high pCO2

Answer 40

F

low both
