Print on Demand. This book unravels the intricate functioning of the heart, our body's motor of life. Historically, the heart and its connection to the overall circulatory system was not fully understood until the 17th century, leading to inaccurate assumptions. The author explores the organ's structure, analyzing the interconnected chambers and valves that ensure the efficient pumping of our lifeblood. Moreover, the book investigates the rhythmical and dynamic relationship between the heart and the circulatory system, highlighting the crucial role of nerves in regulating blood pressure and maintaining the body's vital functions. Beyond its physiological significance, the book delves into the profound influence of emotions on this vital organ, demonstrating how our feelings can have physical manifestations in the form of blushing, palpitations, or even temporary heart stoppage. The author draws upon vivid anecdotes and scientific research to paint a comprehensive portrait of the heart, offering a deeper understanding of its fundamental role in sustaining life. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. …

The whole quantity of blood in the body has been reckoned at about one-fourteenth part of the weight of the body; the blood in the body of a man weighing fourteen stone Will therefore amount to one stone, or fourteen pounds. If we accept this as a probable average of the weight of blood in the body, then as fourteen pounds amount to 224 ounces, and as the left ventricle contains, as we suppose, only 3 ounces, it follows that the whole blood of a man weighing 196 lbs. Passes through his left ventricle in nearly 75 of its systoles or contractions. And as we suppose the heart to contract only 70 times in a minute, then the whole of the blood of such a man passes through his heart 48 times in one hour, or 1152 times in one day. Of course the length of time that the Whole of the blood in a man takes to pass through his heart depends upon three factors, - first, the actual amount of blood he possesses; second, the size of his ventricular cavity; and thirdly, the rate of its pulsation.
