The organ that calculates the changing needs of the foetus and responds to these needs without deficiency
is the placenta. The cells in the outer layer of the placenta form a kind of filter between the mother's blood
vessels and the foetus. For example, while permitting the passage of nutrient material, they deny entrance
to the elements of the defensive system. The placenta is composed of cells. How do these cells know what
the foetus needs? How do they understand what cells they must protect the foetus from? How do they dis-
tinguish what the embryo needs from among millions of molecules? Who gave this expert ability to the
piece of flesh called the placenta and to the cells of which it is composed? It is surely God Who has taken
all precautions so that the baby may survive and has created a system in the body for this purpose. God is
Well-versed in every kind of creation.
