The movement of fluid across the arterial end of capillary membranes into the interstitial fluid surrounding the capillary is an example of which process of fluid movement?

B)Osmosis
C)Diffusion
D)Active transport

Hydrostatic pressure is the mechanical force of water pushing against cellular membranes. In the vascular system, hydrostatic pressure is the blood pressure generated in vessels by the contraction of the heart. Blood reaching the capillary bed has a hydrostatic pressure of 25 to 30 mmHg, which is sufficient force to push water across the thin capillary membranes into the interstitial space.
