There is a whirl of words spoken by Don Clemente, by the lad Alberti, by the elderly Englishwoman, while fragments of the Vision flash like pictures before his mind's eye. Yes, he will go to Casa Selva, but only for a short time. As he ascends, the mighty voice of the Anio roars louder, ever louder, out of the depths: "Rome! Rome! Rome!" JEANNE TO NOEMI. VENA DI FONTE ALTA, July 4,
The vena cava was on the left side and passed into the pulmonary cavity of the heart, which was also on the left side, the aorta and systemic ventricle being on the right. The left splenic vein was lying on the superior vena cava, the liver under the left ribs, and the spleen on the right side underneath the heart.
In each organ separation and purification of the blood are effected and removal of the heterogeneous, not to mention how the heart sends its blood up to the brain after purification in the lungs, which is done by the arteries called carotids, and how the brain returns the blood, now vivified, to the vena cava just above where the thoracic duct brings in the chyle, and so back again to the heart.
The first movement was made by Niccolo Piccinino, who being informed that if he attacked Vico Pisano by night, he could easily take possession of the place, made the attempt, and having failed, ravaged the surrounding country, and then burned and plundered the town of San Giovanni alla Vena.
Galen adduces this argument for the transit of the blood by the right ventricle from the vena cava into the lungs; but we can use it with still greater propriety, merely changing the terms, for the passage of the blood from the veins through the heart into the arteries.
As regards the bow, again, O chastiser of foes, it was Prithu who first created it. It was with the aid of this weapon that that son of Vena, while he governed the earth virtuously for many years, milked her of crops and grain in profusion. It behoveth thee, O son of Madri, to regard what the Rishis have said, as conclusive proof. All persons skilled in battle should worship the sword.
The way the ancients looked at this matter was, that the food, after being received into the alimentary canal, was then taken up by the branches of this great vein, which are called the 'vena portae', just as the roots of a plant suck up nourishment from the soil in which it lives; that then it was carried to the liver, there to be what was called "concocted," which was their phrase for its conversion into substances more fitted for nutrition than previously existed in it.
When the foetus is farther advanced, when the bones can be distinguished from the fleshy parts and movements take place, then it also has a heart which pulsates, and, as I have said, throws blood by either ventricle from the vena cava into the arteries. These points will be found elsewhere confirmed by numerous observations on the formation of the foetus.
I have, however, cogitating with myself, seen further, that the same thing obtained most obviously in the embryos of those animals that have lungs; for in the foetus the four vessels belonging to the heart, viz., the vena cava, the pulmonary artery, the pulmonary vein, and the great artery or aorta, are all connected otherwise than in the adult, a fact sufficiently known to every anatomist.
=The Veins or Returning Tubes.= The veins, beginning in fine branches formed by the capillaries, return the blood to the heart. The branches unite into larger and larger vessels and finally flow into one main vein, the vena cava. This extends along in front of the backbone and opens into the heart. =Why the Blood flows in only one Direction.= The heart causes the flow of the blood.
