Document Summary
Chapter 5 overview: homeostasis and body fluid compartments, osmosis and tonicity (on your own; page 132-139) what is it, why is it important. Not calculations how it contributes to homeostasis. Transport processes (membrane properties: diffusion, protein-mediated transport, vesicular transport (on your own; page. 155-157) brief: epithelial transport (peds 103, resting membrane potential (later with chapter 8) Concept check: osmosis and tonicity - page 139 (#6-#10, vesicular transport - page 157 (#27-#29), Diffusion movement of higher [] gradient to lower [] gradient suggests crossing membrane. Next 3 images say the same thing, just different illustrations.

No energy = diffusion going high to low.
