A
  1. Capillary Pressure
  2. Interstitial Fluid Pressure
  3. Plasma Colloid Osmotic Pressure
  4. 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
