INJECTION PRESSURE FOR THE FILTER SYSTEMS

Another major reason for the tightening of the vessels is the need to squeeze the blood volume in the arterial system so that water can be filtered and injected into some vitally important cells in the body, such as the brain cells. The tightening of the blood vessel walls provides the force necessary to operate a reverse osmosis system in the human body - a crisis-management program to keep important cells alive. Water is pushed into selected cells of the body through tiny "shower heads" - cluster perforations in the cell membrane. The difference between the two readings of blood pressure is the range of force needed to deliver water under normal circumstances into some vital cells of the body. As the body becomes more and more dehydrated, the amount of pressure needed to filter and inject water into vital cells increases. The less water there is in the body, the more pressure is needed to hydrate the vital cells.

The mechanism is simple. When confronting stressful circumstances, and in dehydration that is becoming gradually established, histamine is released. Histamine activates the production of vasopressin (an antidiuretic hormone). Certain cells of the body have receiving points that are sensitive to vasopressin. As soon as the hormone sits on the sensitive point, a hallow "shower-head" type of opening with minute holes in its base is created in the cell membrane. Serum fills the space, and its water content filters through the holes, which are large enough for the passage of only one water molecule at a time. Vasopressin, as its name implies, also produces the tightening of the vessels around it. This tightening of vessels translates into a squeeze that pushed the serum and its water through the holes in the blood vessel - a necessary act if some of this water is to be pushed back into the cells.
