- luminal flow rate
- extracellular pH
- aldosterone (K+ secretion)
7
Q
pitting edema
A
increased intersitial fluid volume
8
Q
non-pitting edema
A
increased ICF volume
9
Q
sympathetic effects on glom
A
- aff art const (dec GFR)
- increased renin release
- increased ANG II (GFR stabilization)
10
Q
afferent capillary const
A
- dec RPF
- dec glom fintration P
- dec GFR

Q
efferent capillary const
A
- dec RPF
- increase pressure in bowman’s space
- increased glomerular filtration
- increased GFR
