renal 3

Question 1

vol of ecf reg by

Answer 1

amt of salt in body

Question 2

most of Na available in

Answer 2

ECF

Question 3

pressure or vol inc from Na are detected by

Answer 3

baroreceptors

Question 4

responce of baroreceptors to inc(pressure or vol)

Answer 4

tell kidney to excrete salt

Question 5

load dependent

Answer 5

more Na filtered more resorbed Proxt tubule and Thick ascending limb

Question 6

maintain intak=excretion

Answer 6

distal tube and CD

Question 7

limited capacity for resorption of NA

Answer 7

distal tube and CD

Question 8

tf when u gain or lose NA the first site to be affected is distal segment

Answer 8

T

Question 9

tf when there is loss of salt then more na is resorbed in the prox tubule

Answer 9

T

Question 10

NO acts in NA constraction stimulates na resorption at prox tubulte inh na resorbtion at prox tubule

Answer 10

inh na resorbtion at prox tubule happens when NA inc(ecf expansion)

Question 11

tf symp and ang1 stimulate na resorption at prox tubule when there is loss of NA

Answer 11

F symp and ang2

Question 12

tf NA amt reabsorbed in distal tubule is low

Answer 12

F small percent but large amt

Question 13

which of the following doesnt inh. resorption of NA at distal tubule? no PG ANP ALdosterone

Answer 13

aldosterone inc NA absorption when Na is intaken(ecf expansion)

Question 14

which of the function is function of aldoesteron Na resorption by kidney inc adh sec and leads to water retention more thirst arteriolar vasoconstrictor(restore BP)

Answer 14

Na resorption by kidney other by Ang 2

Question 15

which of following reg how much aldosterone secreted in plasma renin ang1 ang 2 angiotensinogen

Answer 15

renin

Question 16

renin released

Answer 16

from granular cells

Question 17

ANP

Answer 17

inc in high ecf cases(NA intake)

Question 18

TF RAA system inc na excretion

Answer 18

f dec it

Question 19

h20 reabs in prox tubule is

Answer 19

isoosmotic follows NA

Question 20

tf most of water is reabsorbed at prox tubule anddistal tubule

Answer 20

F distal tubule is imperm to water

Question 21

tf passive transport maintain 200 mOsm gradient in the medulle between tubules cells and int fluid

Answer 21

f active transport

Question 22

equilibrates with interstitial fluid

Answer 22

descending limb

Question 23

oblig water loss

Answer 23

.5l / day

Question 24

diuresis

Answer 24

low adh

Question 25

in diuresis osmomolarity is more in cd osmolarity in less in cs salt cant be reabrorb in CD

Answer 25

osmolarity in less in cs because salt is reabsorbed in CD

Question 26

active transport out of ascending limb

Answer 26

concentrate the interstitium

Question 27

action of ADH to reabsorb water at CD needs

Answer 27

loop of henle needed to set up stage of concentrating interstitium

Question 28

wat helps maintain int. molarity

Answer 28

vasa recta

Question 29

adh constrict —-,; results in—- solute in medulla

Answer 29

vasa recta; less

Question 30

adh sec by

Answer 30

post pit

Question 31

tf to restore osmolarity osmorecptors alone are adequate to inc adh

Answer 31

f need to drink h2o

Question 32

tf baroreceptor only inh ADH receptors when you have inc vol

Answer 32

f they are constantly inhibiting ADH receptors

Question 33

tf osmorecptor and baroreceptor both both have adh as effectors

Answer 33

t

Question 34

vol receptor

Answer 34

baroreceptor

Question 35

sense plasma osmolality

Answer 35

osmoreceptor

Question 36

ecf expansion and anp

Answer 36

inh thirst and adh release
