The ability of c-white to increase plasma osmolality indirectly increases blood volume.
However, among the basic factors of blood pressure maintenance, cardiac dynamics, circulatory volume, and vascular resistance, changes in circulating volume may have a relatively small effect on blood pressure due to the fact that most of the body’s volume is stored in the venous system, accounting for approximately 80%
In addition, an increase in plasma colloid osmotic pressure decreases the degree of tissue edema and facilitates the recovery of organ function.
