Question
Chapter 24.4, Problem 5QC
Summary Introduction
To review:
The three pressures that combine for determining the net filtration pressure. The pressure(s) that promote(s) filtration and the pressure(s) that oppose(s) filtration.
Introduction:
Filtration occurs only when there is a pressure gradient which pushes water as well as solutes via the filtration membrane. Two forces namely, COP (colloid osmotic pressure) and hydrostatic pressure act together in a capillary bed for determining the NFP (net filtration pressure) of the bed.
