as an antonym of the word “bubble”. Our attempt to find out through correspondence with
            Mr. Watson gave nothing. In any case, we are grateful to these colleagues for the fact that
            their work inspired us to draw attention to the problems of embryology from the position
            of the newly created theory of cavitation, although it would seem that this area of science
            is “not our path” but, however, “we are now there too!”.

                  4.2.1 Regulation of the formation of blastocysts - cavitations

                  Since the work under discussion is mainly devoted to the consideration of metabolic
            mechanisms at the cellular level, we present several drawings borrowed from. One of
            these mechanisms is the “ion pump”, which generates various vehicles - carriers of ions
            and enzymes. In fig. 5, we see the expression of carriers of ions and enzymes in the
            trophoblast trophoblasts of preimplantation mammalian embryos.




















                            Figure 5. Expression of ion and enzyme carriers in the trophectoderm
                                         mice pre-implantation mammalian embryos.

                  In fig. 6, we can observe the exchange of enzymes catenin and actin, and the same
            zonula exchange mechanism through the inner and outer layers of trophectoderm cells.

                                     zonula occludens (right) in polarized epithelial cells.

                  And  in  fig.  7,  we  observe  one  of  the  most  common  and  extremely  important
            exchange mechanisms - adenosinetriphosphate transport, discovered in 1957 by one of
            the Nobel Prize in Chemistry 1997 Jens Skou [ ].
