DID THAT JUST BEAT??



What makes the HEART BEAT??

It would take a big book to do justice to this question. We know positively that the heart can and does beat in an independent way quite apart from the brain or the rest of the body. The heart of a frog or a bird  or a rabbit, for a instance, can be completely cut out of the body, and will lie beating in the hand for a long time. This proves that what starts the heart beat is in the heart, even though we know the brain can make the heart beat faster or slower, or can even stop it,

When we examine the heart of any animal, we find that it has a large number of nerve cells. If we cut a heart to pieces, any part which is cut away from  the nerve cells stops beating, but any part which has nerve cells in it will go on beating until the heart dies from lack of energy. It is very interesting that the heart will go on beating for so long. If we attach tubes to the heart in place of the blood vessels, and send fluids through it containing common salt and certain other salts which help to nourish it, it will continue to beat steadily for hours or even days. In this way we can study the action of different things on the heart; and it has thus been proved that sugar is a valuable heart food, while alcohol is no food to the heart at all .
