Question
Chapter 21, Problem 11RQ
Summary Introduction
Introduction:
The capillary action is dependent on two factors namely the hydrostatic pressure and the osmotic pressure. Both these factors play an essential role in the movement of water through the capillary. The hydrostatic pressure pushes substance out of capillary while the osmotic pressure brings substances into the capillary.

What forces drive fluid to move OUT of capillaries and INTO capillaries?
What is colloid osmotic pressure? In which direction does colloid osmotic pressure drive the movement of water in a capillary?
Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans. If blood pressure at the venous end is about 15 mm Hg, and colloid osmotic pressure is 25 mm Hg throughout, what is the net effect on fluid movement between capillaries and tissue spaces?
