How does a completely separate person live inside another person? That’s the job of the Placenta!
18 The one who guards [tends] a fig tree will eat its fruit, and whoever protects their master will be honored.
Yesterday, we discovered that when a fertilized egg (a zygote) divides, one half becomes the placenta and the other half becomes the baby. The placenta cell begins to make more cells that surround the baby cells and basically form a cocoon, which sticks to the uterine wall to receive nourishment. All this happened by “accident,” right? This next part is doubly amazing! From, “A Pocket Guide to the Human Body,” (pages 90-94).
Although the developing placenta and baby implant within the thick nutrient-filled wall of the mother’s uterus, they are not actually part of the mother’s body. One of the placenta’s important roles is to protect the developing baby from an attack by the mother’s immune system, since the baby and the placenta are genetically unique and distinctly different from the mother. It is still a mystery how the placenta prevents the mother from rejecting it and the baby as a foreign graft without shutting down her immune system.
After implantation, the placental giant cell “invades” the walls of several uterine arteries and veins, causing the mother’s blood to flow through channels within the cell (see figure 3).
When the baby develops its own blood and blood vessels, the mother’s blood and the blood of the developing baby come into close association, but they never mix or come into direct contact [AMAZING!]. The syncytial trophoblast forms a thin, seamless, and selective barrier between maternal blood and fetal blood. All the critically important nutrients, gasses, hormones, electrolytes, and antibodies that pass from mother’s blood to the baby’s blood must travel across this seamless and selective filter. Waste products in the baby’s blood must, in turn, pass across this filter to the mother’s blood.
From this point on, Mom is hostess to her baby. Provided with opportunity, this little mass of cells that is inside the placenta ball will grow into a full-sized adult one day. From the moment the sperm fertilized the egg, God designed that zygote to be a human being! God is the Creator of all nature and He acts naturally: When we fertilize an egg, we get a human being. With all of our science, why is this “concept” so difficult to acknowledge and accept?
Abba, thank You that all things are from You and through You and to You (Romans 11:36). All humans belong to You, whether zygotes or senior adults. You have saved us through Your amazing power, the power You exerted when You raised Christ Jesus from the dead and seated Him next to You (Ephesians 1:19-20). To You be glory in the church and in Christ Jesus throughout all generations, for ever and ever! Amen (Ephesians 3:21).
