THE MIRACLE OF THE
BLOOD AND HEART
A cardiogram
indicating the
heart's electri-
cal activity. The
heart beats
rhythmically
and synchroni-
cally. Thanks to
this regular
rhythm the
body is provid-
ed with the
appropriate
amount of
blood flow.
The Heart Cells' Timing
The impeccable order in the timing of the heart is brought
about by coordination and communication among the cells
that comprise it. Here again, of course, a striking intelligence
manifests itself. These intelligent cells transmit current to the
other side of the heart at a speed of approximately 60 cen-
timeters (23.62 inches) a second. The signal is sent from the
sinus node. The cells comprising the sinus node produce the
th
signal in 1/14 of a second.
As the current moves rapidly, it passes through the
two atria in turn and causes them to contract.
