... colour and its capillaries finely injected, was full of yellow serum. The lining membrane of the larynx and trachea was of a greenish-yellow colour throughout, and in the spaces between the cartilages ulcerated and disorganized in several spots. Beneath the membrane was a venous injection. About the bifurcation it was injected; and in the ramifications of the trachea were seen several inflamed, and in places abraded and disorganized spots. A chocolate coloured liquor with a sediment filled the bronchiae and ...

... disarrangement. From all cities, hamlets, from the utmost ends of this France with its Twenty-five million vehement souls, thick-streaming influences storm in on that same Heart, in the Salle de Manege, and storm out again: such fiery venous-arterial circulation is the function of that Heart. Seven Hundred and Forty-nine human individuals, we say, never sat together on Earth, under more original circumstances. Common individuals most of them, or not far from common; yet in virtue of the position they occupied, so notable. ...

What are the lymphatics? What do they contain, and what is their purpose? What are ...

... going on. The nervous and muscular spasmodic contraction of the diseased anus and rectum, which in time become more or less permanently constricted, steadily increases the stagnation and engorgement of blood in the dilated arteries, veins, arterioles, venous rootlets and capillaries. All of the circulatory vessels, especially the smaller ones, become enlarged, varicose; and an aggregation of varicosed vessels forms a tumor called a pile or hemorrhoid. Inflammation interferes with nutrition of the anal and ...

... earth's crust. This invisible gas, this breath of air, through the magic of chemical combination, forms nearly half the substance of the solid rocks. Deprive it of its affinity for carbon, or substitute nitrogen or hydrogen in its place, and the air would quickly suffocate us. That changing of the dark venous blood in our lungs into the bright, red, arterial blood would instantly cease. Fancy the sensation of inhaling an odorless, non-poisonous atmosphere that would make one gasp for breath! We should be quickly poisoned by the waste of our own bodies. All things that live must have oxygen, and all things ...

... into every part of the body. Between the ultimate ramifications of the arteries and the beginning of the veins there is an intermediate system of very minute vessels called capillaries, which connect the arterial with the venous system of the circulation. The walls of the arteries are possessed of a certain amount of rigidity, sufficient to keep the tubes open when ...

Of the two kinds of blood, the one, contained in the venous system, was dark and thick and rich in grosser elements, and served for the general nutrition of the body. This system took its origin, as is clearly shown in the figure, in the liver, the central organ of nutrition and of sanguification. From the portal system were absorbed, through the ...

... the alimentary tract, was absorbed as chyle from the intestine, collected by the portal vessel, and conveyed by it to the liver. That organ, the site of the innate heat in Galen's view, had the power of elaborating the chyle into venous blood and of imbuing it with a spirit or pneuma which is innate in all living substance, so long as it remains alive, the natural spirits (πνευμα φυσικον {pneuma physikon}, spiritus naturalis of the mediaevals).

The atoms of this extra oxygen are transmuted into life current to rejuvenate the brain and spinal centers. {FN26-1} By stopping the accumulation of venous blood, the yogi is able to lessen or prevent the decay of tissues; the advanced yogi transmutes his cells into pure energy.

... called pores of the skin. They descend into the true skin, and there form a coil, as is seen in the drawing. These tubes are hollow, like a pipe-stem, and their inner surface consists of wonderfully minute capillaries filled with the impure venous blood. And in these small tubes the same process is going on as takes places when the carbonic acid and water of the blood are exhaled from the lungs. The capillaries of these tubes through the whole skin of the body are thus constantly exhaling the noxious and decayed particles of the body, ...

... more important for the health or healing of any organ or part of the body than a good supply of arterial blood. Venous blood, collected by the veins after it has done its work all over the body, or blood stagnating in congested organs, is useless for growth and healing.

And all Harvey's predecessors further agree in the belief that only a small fraction of the total mass of the venous blood is conveyed by the vena arteriosa to the lungs and passes by the arteria venosa to the left ventricle, thence to be distributed over the body by the arteries. Whether some portion of the refined and "pneumatic" arterial blood traversed the anastomotic channels, the existence ...
