Physics of a Heartbeat
Behold the Heart
The heart is something that has been written about for thosands of
years. It is something of legend and lore and the very thing
we just a life by. The very fact that a heart can beat on
its own through electrical impulses is actually quite

intricacies of its motion.
heart does not simply function by electricity though. The
heart has many feedback mechanisms such as hormones, blood
temperature that keeps the heart beating regularly through times
of rest, exercise and times of fight or flight.
In this page, I will discuss the electrical aspects of the heart,
how the electrical impulse propogates, how it then travels through
and how it terminates.
Furthermore, I will disscuss two other main points. These
being, the fluidity and pressure of the blood moving through the
as well as how energy is conserved through the beating of the
