76 THE MIRACLE OF ELECTRICITY IN THE BODY

increases its tempo to pump around 2,270 liters (560 gallons) of blood an
48
hour. That is because our muscles need more oxygen when performing
tiring activities. Under such circumstances, the heart increases its work-
ing tempo from 70 to 180 times a minute, and the level of blood reaching
the tissues can increase five-fold.
No man-made pump can match the heart’s ability to work tirelessly
for an entire lifetime and to regulate the quantity pumped according to
prevailing circumstances. The extraordinary nature of the heart reveals
an important fact. God created many matchless structures, such as the
heart, in the billions of human beings. And as revealed in the Qur’an,
this is an easy matter for Him:
Your creation and rising is only like that of a single self. God is All-
Hearing, All-Seeing. (Surah Luqman, 28)

The heart carries blood and all
essential substances to the
cells throughout the body, and
when it can no longer function,
death ensues. Like all other or-
gans in the body, it runs on
electricity; but this energy that
allows the heart to beat does
not come from outside, but is
produced with the contraction
of the heart muscles. Since the
heart consists almost entirely of
muscle, and beats around 70
times a minute, then an electri-
cal impulse needs to be pro-
duced that many times. Its tire-
lessly contracting muscle cells
possess a special creation to
work the moment an electrical
current reaches them. The
heart, which is made up of
these special cells, is an engine
that creates its own energy.
This astonishing system in the
heart is created by God, the
Creator of all things.
