D. All of the answers

Explanation:

Materials can move across capillary walls by diffusion, filtration and reabsorption. Gases such as oxygen move across by diffusion, which is controlled by the difference in pressure. Fluid moves across the tube through osmotic pressure which is exhibited by the filtration and reabsorption process
