I, and indeed others, have sometimes found valves in the emulgent veins, and in those of the mesentery, the edges of which were directed towards the vena cava and vena portae.
That mastery of phrase is astonishing. From the silver beauty of the moonlit line from his Melanippe Lumine sic tremulo terra et cava caerula candent, to the thunderous oath of Achilles Per ego deum sublimas subices Umidas, unde oritur imber sonitu saevo et spiritu they give examples of almost the whole range of beauty of which the Latin language is capable.
The veins had their origin in the liver; the superior vena cava communicated with the right heart, and, as Galen taught, some blood was distributed to the lungs; but the two systems were closed, though Galen believed there was a communication at the periphery between the arteries and veins.
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.
We were received by Miss Whyte, an English lady who has settled at La Cava, and she afforded us the warmest hospitality that is consistent with a sadly cold chilling house.
So it clearly appears in the case of the foetus that the heart by its action transfers the blood from the vena cava into the aorta, and that by a route as obvious and open, as if in the adult the two ventricles were made to communicate by the removal of their septum.
Inferior vena cava. 6. Renal arteries. 7. Renal veins. *Structure of the Kidneys.*—Each kidney is a compound tubular gland and is composed chiefly of the parts concerned in secretion. The ureter serves as a duct for removing the secretion, while the blood supplies the materials from which the secretion is formed.
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.
That in one sense he was right the jugular, which the other had probably opened, runs into the vena cava, and may, with some latitude, be considered a superior branch of it; therefore, thus far the first man had punctured the vena cava, which I had done many hundred times; but that the point of union of the four principal veins that form the vena cava was too securely seated in the upper part of the thorax for any lancet to reach it.
Excessive growth; thickening or enlargement of any part or organ. Applied to the four front teeth of both jaws, which have sharp, cutting edges. Incus. An anvil; the name of one of the bones of the middle ear. Indian Hemp. The common name of Cannabis Indica, an intoxicating drug known as hasheesh and by other names in Eastern countries. Inferior Vena Cava.
