Question

Materials can move across capillary walls by _________.a. reabsorption. b. diffusion. c. filtration. d. All of the answers are correct. e. None of the answers is correct.

Answer 1

Answer:

The correct option is D) All of the answers are correct.

Explanation:

The walls of the capillaries are thin due to which the processes of diffusion and filtration becomes lot easier in them. Gases such as oxygen and carbon dioxide cross the capillary walls through diffusion processes. As the walls of the capillaries are much thinner than that of veins and arteries hence. the processes of filtration and re absorption occur easily through them.
