its chambers. Therefore, how is this valuable organ nour-
ished?
In addition to all the marvels of creation examined so far,
the heart is also nourished by a special system that feeds it,
known as the coronary circulation.
Of the blood that emerges from the heart by way of the
coronary arteries, the heart itself is the first recipient. These
arteries are two separate branches of the aorta carrying oxy-
gen-rich blood from the lungs. These arteries have been creat-
ed solely to feed the heart. Unlike all the other arteries, they
leave the heart but then return to it, rather than going to other
organs. In this way, the blood richest in oxygen is devoted to
nourishing the heart, that region of the body needing the
greatest amount of oxygen, without being diverted anywhere
else. Since the heart's cells must turn oxygen and sugar into
energy in order to be able to function, blood in the coronary
arteries needs to be rich in these substances—because the
heart's energy consumption is regulated according to need,
and can raise four- or five-fold in a matter of seconds. 98
The coronary arteries are perfectly equipped for their job.
These arteries entering the heart separate into much smaller
branches and spread throughout the heart muscle. Every cell
making up the heart has a constant need for nutrients and
oxygen. As these arteries head directly for the heart, they also
establish sub-connections with one another, because if any of
the arteries is blocked for any reason, the heart muscle will
receive no nourishment and will die. These sub-connections
represent a precaution taken in the face of that very
grave danger. If one artery becomes blocked, thanks
