THE MIRACLE OF THE
BLOOD AND HEART
in binding with hemoglobin, and the higher acidity of the oxy-
genated hemoglobin promotes dissociation of carbon dioxide
from the hemoglobin to which it is attached. 27
This chemical process is exceedingly complex. The point
that needs emphasis is that the sites where hemoglobin
exchanges oxygen and carbon dioxide have been determined
with the greatest sensitivity. Hemoglobin must release oxygen
in the tissues and load up with carbon dioxide, and in the
lungs—the exit point for carbon dioxide—the reverse of this
exchange takes place. This exchange takes place nowhere else
in the body. The chemical balance that maintains this cycle has
to be fully functional at the same time as the circulation of the
blood, and cannot possibly have evolved gradually, over the
course of time, through random mutations.
Sometimes hemoglobin in the blood binds with carbon
monoxide instead, generally through external influences, in a
phenomenon known as carbon monoxide poisoning. If carbon
monoxide (CO) gas from the incomplete combustion of coal or
car exhausts is inhaled, it binds to hemoglobin and thus
replaces the oxygen that is—or will be—attached to the hemo-
globin. Hemoglobin is more "attracted" to carbon monoxide
than it is to oxygen, and binds to it 500 times more tightly than
it does to oxygen. If enough CO is inhaled, this can lead to
death from oxygen deprivation. 28
The Miraculous Iron inside the Hemoglobin
The iron in hemoglobin, which plays a major role in the
process of oxygen transport, is one of the great miracles
created by God. Iron, which enters the body by vari-
