Textbook Question
Chapter 47, Problem 5U
Fick’s Law of Diffusion states the rate of diffusion is directly proportional to
a. the area differences between the cross section of the blood vessel and the tissue.
b. the pressure differences between the two sides of the membrane and area over which the diffusion occurs.
c. the pressure differences between the inside of the organism and the outside.
d. the temperature of the gas molecule.

Provide a definition for diffusion.
In terms of their effect on the rate of diffusion, which of the following is the odd one out?
a) decreasing the surface area of the membrane
b) decreasing membrane permeability
c) decreasing lipid solubility of the diffusing molecule
d) decreasing the concentration gradient of the diffusing molecule
e) decreasing the thickness of the membrane
Active tissues generate carbon dioxide, which diffuses out of the tissue into the bloodstream, to be carried away. Is this diffusion into the blood a case of flow up a gradient, or down? Explain.
