The blood enters the auricles and then pours through an opening into each ventricle, from which it passes out into the arteries. =The Arteries or Sending Tubes.= The blood is sent out from the heart through the arteries leading to all parts of the body. The chief artery is the aorta. It is larger than your thumb and extends from the heart down through the body in front of the backbone.
The heart may now be severed from the lungs by cutting the large blood vessels, care being taken to leave a considerable length of each one attached to the heart. Observe the outside of the heart. The thick, lower portion contains the cavities called ventricles; the thin, upper, ear-shaped portions are the auricles.
The auricles often beat many times more frequently than the ventricles, even two or three times as frequently, and, of course, these auricular contractions are not transmitted to the arterial system, and the radial pulse notes only the contractions of the ventricles. The phrase that is used to describe this nontransmission of the auricular stimulus to the ventricles is "heart block."
You wish to be so ranked among the people and things that lead the age; consider the qualities you must have, and while you consider, keep your eye on Richard Wade, for he has them all in perfection. First, of your physical qualities. You must have lungs, not bellows; and an active heart, not an assortment of sluggish auricles and ventricles. You must have legs, not shanks.
And this occurs in the following manner: There are, as it were, two motions going on together: one of the auricles, another of the ventricles; these by no means taking place simultaneously, but the motion of the auricles preceding, that of the heart following; the motion appearing to begin from the auricles and to extend to the ventricles.
The large, short vein that drains the liver and adjacent parts. Ven'tri cles. The two chambers of the heart that receive blood from the auricles and force it into the arteries. Air cells. The cells, or cavities, that line the air passages and air sacs at the ends of the bronchial tubes. Breath.
But this especially is to be noted, that after the heart has ceased to beat, the auricles however still contracting, a finger placed upon the ventricles perceives the several pulsations of the auricles, precisely in the same way and for the same reason, as we have said, that the pulses of the ventricles are felt in the arteries, to wit, the distension produced by the jet of blood.
The ventricles, having in this way been fully charged by the auricles, now contract and force their contents into the large arteries. *Sounds of the Heart.*—Two distinct sounds are given out by the heart as it pumps the blood. One of them is a dull and rather heavy sound, while the other is a short, sharp sound.
For hence all the arteries of that organism draw their life, and on the systole and diastole of the Base, on the contractions and dilatations of its auricles and ventricles, the Army depends for its circulation. To and from the Base come and go in endless tributaries men, horses, supplies, and ordnance. The Base feeds the Army, binds up its wounds, and repairs its wastage.
And this leads me to remark that he who inquires very particularly into this matter will not conclude that the heart, as a whole, is the primum vivens, ultimum moriens, the first part to live, the last to die, but rather its auricles, or the part which corresponds to the auricles in serpents, fishes, etc., which both lives before the heart and dies after it.
