The body is constantly striving to maintain the proper balance of __ & ___.
Fluids and electrolytes.
There is a broad or narrow spectrum for the electrolytes? As in, a lot (or a little?) can change before a problem occurs?
A little! There is a very small range.
Functions of Body Fluid - what are some of them?
Medium for transport & exchange of nutrients/other substances, medium for metabolic reactions, solvent, provides structure, provides insulation, etc.

2+ - 4mm
3+ - 6mm
4+ - 8mm
What is an example of non-pitting edema?
Lymphedema
What are some causes of edema?
Increased capillary permeability, increased capillary osmotic pressure, increased hydrostatic pressure, lymphatic obstruction.
Capillary Permeability - info?
Think of this as when the capillaries become damaged - they can leak!
Hydrostatic Pressure - pressure of what?
Pressure of fluid!
