                  Important moment, normalizes metabolism at the cellular level is the formation of
            blastocoels - the liquid filling of the blastocyst, the main component of which is water. In
            fig. 8 we see three possible mechanisms for the accumulation of water in the blastocoel...

















                          Figure 8. Mechanisms of water movement through biological membranes.
                             Water usually crosses the lipid bilayer through:   i) simple diffusion;
                            ii) co-transport during the transfer cycle of enzymes and other carriers;
                                              iii) through the expression pores.

                  From the above observations of metabolic mechanisms, what can we conclude about
            the role of cavitation in a certain sense? First of all, we must emphasize the foresight of
            the authors of work , namely, those who called the formation of the blastocyst - cavitation.
            Of course, they had in mind the appearance of the bladder of the paired concept of the
            blastocyst-trophectoderm, the trophectoderm as a bubble envelope, and the blastocyst as

            its internal contents. But, as they say, the truth was somewhere nearby, and we are going
            to reveal it, using the final statements of the authors :
                 - trophectoderm acquires the ability to initiate and regulate cavitation events, forming
            gene products that facilitate transportation and retention of the blastocoeline fluid as the
            blastocyst accumulates in the nascent cavity ; in other words, here the main role is played
            by cavitation, we will clarify our thought: the easiest and easiest way for genic products,
            including water mixture, to leak through the membrane, and its role is played by layers
            of trophectoderm cells - the formation of gas bubbles, with a high content of air, these
            bubbles adhere to the membrane and at any opportunity, say under the action of osmotic
            pressure, these bubbles are indented through the pores of the membrane, collapsing on
            the opposite side, thereby entering the cavity of the blastocyst and Products consisting
            mainly of ions of various chemical elements (ChE) and salts, enzymes, as well as the
            water  mixture  that  constitutes  the  shell  of  bubbles,  here  we  must  also  assume  the
            possibility of formation of bubbles purely in a gaseous medium, as is the case in the air
            inside  a  functioning  RHP  (Ranque-Hilsch  pipe  is  the  main  basic  element  of  IHS
