The total body water is divided into intracellular and extracellular fluids. Plasma is considered __.
The main intravascular fluid in mammals is blood, a complex fluid with elements of a suspension (blood cells), colloid (globulins) and solutes (glucose and ions).The average volume of plasma in the average (70 kg) male is approximately 3.5 liters.he intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membrane. About two thirds of the human body's water is held in its cells and the remainder is found in the extracellular compartment.
