The Microcirculation and Lymphatic System Flashcards
1
Q
Four Primary Hydrostatic and Colloid Osmotic Forces
A
- Capillary Pressure
- Interstitial Fluid Pressure
- Plasma Colloid Osmotic Pressure
- Interstitial Fluid Colloid Osmotic Pressure
2
Q
[Fluid Flow]
Capillary Pressure (Pc)
A
Outward through the membrane
3
Q
[Fluid Flow]
Interstitial Fluid Pressure (Pif)
A
Inward: When it is positive
Outward: When it is negative
4
Q
[Fluid Flow]
Plasma Colloid Osmotic Pressure (IIp)
A
Inward through the membrane
5
Q
[Fluid Flow]
Interstitial Fluid Colloid Osmotic Pressure (IIif)
A
Outward through the membrane
6
Q
What happens when net filtration pressure is positive? What happens if it is enegative?
A
(+): Net fluid filtration across capillaries
(-): Net fluid absorption across capillaries
7
Q
Net Filtration Pressure Equation
A
NFP = Pc - Pif - IIp + IIif
