Summary Introduction

To review:

The overall net filtration pressure in capillary, and whether it is the net absorption or the net filtration that takes place in the capillary.

Introduction:

The colloid osmotic pressure gradient is created due to different concentrations of solutes in the blood and the capillary. The colloid osmotic pressure draws the water inside the capillary because less solute is present in the interstitial fluid and more solute is present in the blood. The hydrostatic pressure moves the water out of the capillary because the hydrostatic pressure inside the capillary is more as compared to the hydrostatic pressure inside the interstitial fluid.
