Question

The most important force causing net outward water flow across capillary walls is ________. Question 19 options: 1) osmotic pressure of plasma proteins 2) hydrostatic pressure of capillary blood 3) hydrostatic pressure of interstitial fluid 4) intracellular hydrostatic pressure

Answer 1

2) hydrostatic pressure of capillary blood

Step-by-step explanation:

Hydrostatic pressure is the type of pressure exerted by any fluid in a confined space.

This force of hydrostatic pressure simply means that when blood moves along the capillary, fluid which contain nutrients and other basic substances are usually moved out through its pores and into the interstitial space.
