The heart works just as speedily to answer the cry of danger once we should act in a very bonafide emergency, because it does once we simply imagine ourselves in some peril. That is why continual emotional upsets place so severe a strain on the heart; the cry “Facilitate, help!” keeps coming from the mind, and the heart keeps responding.

It contracts, squeezing the blood from the four heart chambers into the arteries, then it relaxes, permitting the “oxygen-recharged” blood to flow into the chambers preparatory to the next dispatch of blood throughout the arteries.
