The cell cluster moves towards the secure place prepared for it and continues to divide from day to day. Every 30 hours a division takes place. Dividing exponentially by 2, 4, 8, 16, etc., the cells gradually come to form a small cluster; moving together with unsuccessful sperm cells, it goes slowly from the fallopian tube towards the uterus.
If you magnify the fallopian tube and examine what happens in it, you will see what appears to be the bottom of the ocean. This cluster of cells can continue on its way because of the undulating movement in the fallopian tube. This movement, which had assured the fertilisation of the egg by pushing the sperm towards it, this time carries the egg to the uterus. Small hairs (cilia) found on the surface of the cells of the fallopian tube move in the same direction. In this way, they carry the egg cell as if carrying a very precious object, towards the place where it must go.
Here, as if all the elements involved in this function have received a command from a common centre, they begin at once to work towards the same goal. This command is such that very different areas of the body perceive it and carry it out. While it is in the fallopian tube, the cluster of cells goes through a number of stages of division. A cluster of about 100 cells enters the uterus. But in order to effect this division, the cells must be nourished. This requirement can be regarded as an important aspect of the miracle of human creation.
God has created the fallopian tube so as to respond to the needs of the zygote. In this waiting period, secretory cells alternate with the small hair-like cells lining the fallopian tube. The secretory cells produce large quantities of secretions including organic molecules, ions and water for the nutrition of the zygote.24
"…the uterus increases in size to protect the embryo. The fallopian tubes do what is necessary to nourish the cells…" In sentences like these we have spoken up to this point about the tissues and organs that protect the cell cluster that formed after the egg and the sperm united, take the appropriate measures to ensure its nourishment and work to accommodate these cells. It must not be forgotten that these organs and tissues are also composed of cells. So, how can it be that one cell can sense the need of another and, at exactly the right time, undergo the changes required to nourish and protect it?
When we consider this question, the first answer that comes to mind will be that there is an intelligence that controls the cells. No one will think of a fairy tale in which "one day the cells begin to undergo a change by chance and that afterwards these cells somehow become able to produce the nourishment required by the zygote, then go on to sustain these wondrous occurrences that happen in all women." It is clear that anyone who makes this claim will be accused of fabrication. The preparations that the uterus makes to accommodate the embryo and the particular characteristics of the fallopian tubes which allow them to provide nourishment for the zygote, are operations which exist only in the knowledge of God. Each one of these things is a manifestation of the compassion and mercy that God has for every living thing in His perfect creation.
