Physio Exam 5 Set 2 Flashcards
1
Q
C.O
A
5L/min
2
Q
Renal Blood Flow (RBF)
A
1.2L/min (1/4 of C.O)
3
Q
Renal Plasma Flow (RPF)
A
600ml/min
- AFFECTS ALL RENAL FUNCTIONS
4
Q
Arterial Input =
A
Venous Output + Urine Output
5
Q
Concentration x Flow =
A
Amount
6
Q
GFR
A
Volume of plasma flow into the renal epithelia
- 120 ml/min
(1/5th of RPF)
20% of RPF filters into glomerular epithelia
7
Q
Filtration Fraction
A
0.2 = GFR/RPF
8
Q
2 Forces Filter Fluid OUT
A
-Glomerular Capillary hydrostatic pressure
-Bowmans Space Oncotic Pressure
9
Q
2 Forces OPPOSE ultrafiltration
A
- Bowmans Space Hydrostatic Pressure
- Glomerular Capillary Oncotic Pressure
10
Q
More Renal PLasma Flow
A
More Urine Produced
11
Q
Efferent Determines Reabsorption
- Constriction of Efferent
A
-GFR goes up
