Question 1

Glomerular Capillaries

Answer 1

filters plasma into nephron
makes tubular fluid
fed by afferent, drained by efferent arteriole

Question 2

Peritubular Capillaries

Answer 2

fed by efferent

needed for reabsorption and secretion

Question 3

Filtration

Answer 3

filter plasma to make tubular fluid (urine)

Question 4

Filtered Load

Answer 4

amount filtered in capillaries

Question 5

Excretion

Answer 5

removed in urine

what is left in nephron after filtration

Question 6

Reabsorption

Answer 6

move solute/ water back into blood

Question 7

Secretion

Answer 7

move solute from blood to tubular fluid

Carbonic Anhydrase Inhibitor

Answer 16

diuretic affecting PCT

Question 17

Furosimide

Answer 17

diuretic affecting Loop of Henle

Question 18

Collecting Ducts

affect Collecting Ducts

Question 20

Renal Input

Answer 20

Renal Artery

Question 21

Renal Output

Answer 21

Renal Vein and Ureter

Question 22

Clearance

Answer 22

how much plasma has solute removed in 1 min

determine amount of plasma filtered and amount of blood delivered to kidney

Question 23

Clearance Formula

Answer 23

Xu * V / Xa

Question 24

Clearance of Inulin

Answer 24

Glomerular Filtration Rate
amount of plasma filtered
inulin is only filtered

Question 25

Clearance of PAH

Answer 25

Renal Plasma Flow
100% filtered and 100% secreted
how much plasma moved through kidney

Question 26

Filtration Fraction

Answer 26

amount of plasma filtered by kidney

=GFR/RPF

Question 27

Free Water Clearance

Answer 27

how much water is excreted

vol of all solutes removed

Question 28

High Plasma Osmolarity

Answer 28

excrete as little water as possible

dilute solutes

Question 29

Low Plasma Osmolarity

Answer 29

excrete lots of dilute water

Question 30

Free Water Clearance Formula

Answer 30

Cosm= (Uosm * V) / Posm

Question 31

Positive Free Water Clearance

Answer 31

more water cleared than solutes

because body overhydrated, ECF osmol low

Question 32

Negative Free Water Clearance

Answer 32

more solute cleared than water

because body dehydrated, ECF osmol high

Question 33

Uosm&raquo_space;> Posm

Answer 33

Negative Cwater

need to keep water in body

Question 34

Uosm «< Posm

Answer 34

Positive Cwater

need to lose water
