Net Filtration Pressure (NFP)
Net Filtration Pressure (NFP)
The overall pressure that determines whether fluid will leave or enter a capillary.
Study Notes
- Net Filtration Pressure (NFP) determines whether fluid leaves or enters a capillary.
- NFP is the pressure difference between forces pushing fluid out (hydrostatic pressure) and forces pulling fluid in (osmotic pressure).
- NFP determines the direction of fluid movement in capillaries.
