Renal

Question 1

Parasympathetic innervation of kidney

Answer 1

Kidney DOES NOT HAVE PARASYMPATHETIC INNERVATION

Question 2

Filtration fraction

Answer 2

RPF (renal plasma flow)

Question 3

What increases filtration fraction?

Answer 3

Vasoconstriction of afferent and efferent

Question 4

FILTRATION FRACTION and ONCOTIC PLASMA PRESSURE

Answer 4

If FF increase: Oncotic pressure increases in peritubular capillary: no filtration

Question 5

Filter load

Answer 5

FL= GFR x Px

Filter load)= (Glomerular filtration rate) x (concentration of substance in plasma

Question 6

Excretion rate

Answer 6

ER= Ux x V

Excretion rate = Urine concentration of substance x Urine flow rate

Question 7

Net transport rate

Answer 7

NTR= FL - ER

Question 8

Clearance

Answer 8

Clearance= ER (Ux x V(Flow))
—-
Px

                 excretion rate
                --------------
           plasma concentration

Question 9

Clearance of glucose

Answer 9

0

Question 10

Clearance of albumin

Answer 10

0

Question 11

Clearance of inulin

Answer 11

Equal to GFR

Question 12

Clearance of PAH

Answer 12

Equal to RPF

Question 13

Maximum transporte of glucose TM

Answer 13

375 mg/min

Question 16

Substance no secreted no reabsorbed

Answer 16

Insulin

Question 17

Substance secreted

Answer 17

PAH and creatinine

Question 18

Renal blood flow

Answer 18

RBF= RPF
—- x HCT
1

RBF= renal plasma flow x Hematocrit
——————
1

Question 19

Highest to lowest clearance of substances:

Answer 19

PAH > creatinine > insulin > urea > Na> glucose = albumin

Question 20

Free water clearance

Answer 20

CH2O= V - Uosm x V
—————
P Osm

Question 21

CH2O +

Answer 21

Hypotonic urine

Question 22

CH2O -

Answer 22

Hypertonic urine

Question 25

What aldosterone does with FeNa?

Answer 25

Decreases FeNa

It stimulates reabsorption, so reduces excretion

Question 26

What does ANP with FeNa?

Answer 26

Increases FeNa

It stimulates excretion
