he hormone vasopressin has yet another ability: It can con-
strict the blood vessels and thus raise blood pressure. This
specially designed security system is yet another proof that
human beings were brought into existence through a special creation. In
order for this system to be able to function at all, wide-ranging planning
has been carried out. Very special receptors that measure blood pressure
are located inside the blood vessels extending from the auricle of the heart
and entering the heart itself.
It is well-known that technological devices must be employed to mea-
sure blood pressure. These instruments are developed through the co-oper-
ation of experts in various different fields, and manufactured using
advanced technology. Yet in our hearts, tiny molecules, invisible to the
naked eye, perform the same task. These consist of molecules with no sen-
sory organs, nor any consciousness with which to perceive whatever they
might feel. How can these receptors measure blood pressure and perceive
the subtle differences? In addition, how did these receptors come to be lo-
cated in the heart, in exactly the right place? The answer to all these ques-
tions reveals the existence of God and the glory of His creation.
