To fulfill their functions, erythrocytes and leukocytes have
                   to travel throughout the whole body. It is impossible for them
                   to do this by themselves, however. Even though cells have
                   various mechanisms that allow themselves to move, still there
                   needs to be a fluid for them to move in. This fluid, which trav-
                   els to every point in our bodies every second, together with
                   the various forms of blood cells, is plasma.
                       Plasma constitutes 55% of the blood. It contains 90% water,
                   along with albumin that is used in regulating that water level,
                   globulin used in transporting vitamins, fibrinogen used in
                   blood clotting, glucose and other nutrients, ions used in regu-
                   lating intracellular fluid pH and levels, fats, amino acids and
                   vitamins, and dissolved gasses such as oxygen, carbon diox-
                   ide and nitrogen. 54
                       With the substances it carries and the properties it pos-
                   sesses, plasma performs vital functions in the body, the most
                      important of which is the carrying of nutrients and wastes.
                          Other important features are allowing blood pressure
                            to remain at a specific level, and heat dispersal. In
                              addition, plasma is responsible for maintaining
