Galen adduces this argument for the transit the blood the right ventricle from the vena cava into the lungs but can use with still greater propriety, merely changing the terms, for the passage the blood from the veins through the heart into the arteries. From Galen, however, that great man, that father physicians, clearly appears that the blood passes through the lungs from the pulmonary artery into the minute branches the pulmonary veins, urged this both the pulses the heart and the motions the lungs and thorax that the heart, moreover, incessantly receiving and expelling the blood and from its ventricles, as from a magazine or cistern, and for this end furnished with four sets valves, two serving for the induction and two for the eduGtion the blood, lest, like the Euripus, should incommodiously sent hither and thither, or flow back into the cavity which should have quitted, or quit the part where its presence was required, and the heart might oppressed with labour in vain, and the office write my report for me the lungs interfered with. Finally, our position that the blood continually permeating paid essay writers from the right the left ventricle, from the vena cava into the aorta, through the porosities the lungs, plainly appears from this, that since the blood incessantly sent from the right ventricle into the lungs the pulmonary artery, and in like manner incessantly drawn from the lungs into the left ventricle, as appears from what precedes and the See the Commentary the learned Hofmann upon the Sixth Book Galen, De Usu partium, a work which I first saw after I had written what precedes. position the valves, i need help with my essay cannot otherwise than pass through continuously. And then, as the blood incessantly flowing into the right ventricle the heart, and continually passed out from the left, as appears in like manner, and as obvious, both sense and reason, impossible that the blood can otherwise than pass continually essay writing service discount from the vena cava into the aorta. Dissection consequently shows distinctly what takes place in the majority animals, and indeed in all, the period their maturity buy masters thesis and that the same thing occurs in adults equally certain, both from Galen's words, and what has already been said, only that in the former the transit effected open and obvious passages, in the latter the hidden porosities the lungs and the minute inosculations vessels.
It therefore appears that, although one ventricle the heart, the left wit, would suffice for the distribution the blood over the body, and its eduction from the vena cava, as indeed done in those creatures that have no lungs, nature, nevertheless, when she ordained that the same blood should also percolate the lungs, saw herself obliged add the right ventricle, the pulse which should force the blood from the vena cava through the lungs into the cavity the left ventricle.
In this way, may said, that the right ventricle made for the sake the lungs, and for the transmission the blood through them, not for their nutrition for were unreasonable suppose that the lungs should require much more copious a supply nutriment, and that much purer and more spirituous a nature as coming immediately from the ventricle the heart, that either the brain, with its peculiarly pure substance, or the eyes, with their lustrous and truly admirable structure, or the flesh the heart itself, which more suitably nourished the coronary artery. OF THE QUANTITY OF BLOOD PASSING THROUGH THE HEART FROM THE VEINS TO THE ARTERIES AND OF THE CIRCULAR MOTION OF THus far I have spoken the passage the blood from the veins into the arteries, and the manner in which transmitted and distributed the action the heart points which some, moved either the authority Galen or Columbus, or the reasonings others, will give in their adhesion.
But what remains said upon the quantity and source the blood which thus passes a character novel and unheard-of that I not only fear injury myself from the envy a few, but I tremble lest I have mankind at large for enemies, much doth wont and custom become a second nature.
Doctrine once sown strikes deep its root, and respect for antiquity influences all men. Still the die cast, and trust in love truth and the candour cultivated minds.
And sooth say, when I surveyed mass evidence, whether derived from vivisections, and various reflections them, or from the study the ventricles the heart and the vessels that enter into and issue from them, the symmetry and size these conduits,-for nature doing nothing in vain, would never have given them large a relative size without a purpose,-or from observing the arrange. ment and intimate structure the valves in particular, and the other parts the heart in general, with many things besides, I frequently and seriously bethought and long revolved in mind, what might the quantity blood which was transmitted, in how short a time its passage might effected, and the like.
But not finding possible that this could supplied the juices the ingested aliment without the veins the one hand becoming drained, and the arteries the other getting ruptured through the excessive charge blood, unless the blood should somehow find its way from the arteries into the veins, and return the right side the heart, I began think whether there might not a AS IT WERE, IN A CIRCLE.

Now, this I afterwards found true website that will write essays and I finally saw that the blood, forced the action the left ventricle into the arteries, was distributed the body at large, and its several parts, in the same manner as sent through the lungs, impelled the right ventricle into the pulmonary artery, and that then passed through the veins and along the vena cava, and round the left ventricle in the manner already indicated. This motion may allowed call circular, in the same way as Aristotle says that the air and the rain emulate the circular motion the superior bodies for the moist earth, warmed the sun, evaporates the vapours drawn upwards are condensed, and de scending in the form rain, moisten the earth again.
By this arrangement are generations living things produced and in like manner are tempests and meteors engendered the circular motion, and the approach and recession the sun. And similarly does come pass in the body, through the motion the blood, that the various parts are nourished, cherished, quickened the warmer, more perfect, vaporous, spirituous, and, as I may say, alimentive blood which, the other hand, owing its contact with these parts, becomes cooled, coagulated, and speak effete. It then returns its sovereign, the heart, as if its source, or the inmost home the body, there recover its state excellence or perfection. Here renews its fluidity, natural heat, and becomes powerful, fervid, a kind treasury life, and impregnated with spirits, might said with balsam. Thence again dispersed. All this depends best online writing service the motion and action the The heart, consequently, the beginning life the sun the microcosm, even as the sun in his turn might well designated the heart the world for the heart whose virtue and pulse the blood moved, perfected, and made nutrient, and preserved from corruption and coagulation the household divinity which, discharging its function, nourishes, cherishes, write my assignment for me quickens the whole body, and indeed the foundation life, the source all action. But these things shall speak more opportunely when come speculate upon the final cause this motion the heart. As the blood-vessels, therefore, are the canals and agents that transport the blood, they are two kinds, the cava and the aorta and this not reason there being two sides the body, as Aristotle has but because the difference office, not, as commonly said, in consequence any diversity structure, for in many animals, as I have said, the vein does not differ from the artery in the thickness its walls, but solely in virtue their distinct functions and uses.
