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.
In man they are more numerous in the left than in the right ventricle, more abundant in the ventricles than in the auricles; and occasionally there appear to be none present in the auricles. They are numerous in the large, more muscular and hardier bodies of countrymen, but fewer in more slender frames and in females.
The offices of the auricles and the ventricles are subverted. The blood is sent forth by the veins, and returns by the arteries. Consequently it is running the wrong way through all her corporeal organism lungs and all. Is it then at all mysterious, seeing that such is the case, that on the other particular of gravitation as well, she should differ from normal humanity?
Then there would come those excoriations of his father telling him that his inability to fix things made him good for nothing and this poison would dart through the ventricles of his heart and finish what the subtleties of drowning in oily, nebulous despair could not immediately do.
*Why the Arteries are Elastic.*—The elasticity of the arteries serves a twofold purpose. It keeps the arteries from bursting when the blood is forced into them from the ventricles, and it is a means of supplying pressure to the blood while the ventricles are in a condition of relaxation.
But in animals all local motion proceeds from, and has its origin in, the contraction of some part; consequently it is by the contraction of the auricles that the blood is thrown into the ventricles, as I have already shown, and from there, by the contraction of the ventricles, it is propelled and distributed.

When the breath bands approximate we have inflation of the ventricles of the larynx, the most important of all the resonance cavities, for when this condition prevails we have freedom of tone, and the inflation of all other cavities.
The bay window projecting into the street, whose interior was so popular among the frequenters of the inn, was closed with shutters, in each of which appeared a heart-shaped aperture, somewhat more attenuated in the right and left ventricles than is seen in Nature.
Consider, farther, the use of the several valves, which are all so arranged that the blood, once received into the ventricles of the heart, shall never regurgitate; once forced into the pulmonary artery and aorta, shall not flow back upon the ventricles.
