Describe the two forces of pressure in
"Colloid Osmotic Pressure"
In vessel: the plasma contains many proteins (b/c they can't escape), thus makes plasma hypertonic. THis attracts WATER and PULLS IN. (H20 moves from HYPO TO HYPER regions).
The blood pressure pushes back, PUSHING OUT.
*this does not effect sugar or oxygen levels-- NO EFFECT ON COMPOSITION, just effects fluid distribution
