This Dose, Being It Is Entered Into A

This dose, being it is entered into a blood current, first of all submits to simple physical laws of its movement. On a venous channel the medical structure moves to heart, therefrom to pulmonary capillaries of a small circle, then again to heart, and, at last, to system of capillaries of the big circle. In these conditions medical structure in the shortest time interval mix up with all weight of circulating blood. From the moment of contact to blood neutralisation of its influences begins. When there was a mixing process, influence of all its elements should stop. The reason of it are extremely small quantities of entered elements in comparison with huge, fluctuating weight of these elements in blood. However throughout this process there is a short period when influence of one and bivalent elements of medical structures prevails over influence of similar elements of blood. This period is caused by the certificate of intravenous influence when there is a direct contact of medical structure with a venous wall.
