1

Net filtration equation

Puf = Pgc - (Pbc - πgc)

2

clearance equation

Cx = (Ux . V) / Px

3

ANP effects

-increases Na+ and H2O excretion

-afferent dilator

-efferent constrictor

-aldosterone

4

ADH effects

-contols H2O & urea permeability of Late DT & CD

5

6 factors controlling H+ secretion

-intracellular pH

-plasma Pco2

-carbonic anhydrase

-Na+ reabsorption

-extracellular K+

-aldosterone

6

5 factors controlling K+ secretion

-extracellular K+

-Na+ reabsorption

-luminal flow rate

-extracellular pH

-aldosterone (K+ secretion)

7

pitting edema

increased intersitial fluid volume

8

non-pitting edema

increased ICF volume

9

sympathetic effects on glom

-aff art const (dec GFR)

-increased renin release

-increased ANG II (GFR stabilization)

10

afferent capillary const

-dec RPF

-dec glom fintration P

-dec GFR

11

efferent capillary const

-dec RPF

-increase pressure in bowman's space

-increased glomerular filtration

-increased GFR

12

acidosis occurs with

hypoventilation and diarrhea

13

alkalosis occurs with

hyperventilation & vomiting

 

14

net gain of one Na+ =

net loss of one K+
