Quizplus · Accepted Answer

The flow of fluid into or out of a capillary is determined by a balance between blood pressure and osmotic pressure. Blood pressure tends to force fluid out of the capillary, while osmotic pressure, due to the presence of proteins in the blood, tends to draw fluid back into the capillary. The net flow of fluid will depend on the relative strength of these opposing pressures at a given point along the length of the capillary.
