I, Berlin, 1901. The views of Empedocles, and especially his doctrine that regarded the heart as the main site of the pneuma, though rejected by the Coan school as a whole, were not without influence on Ionia. This work describes the aorta and the pulmonary artery as well as the three valves at the root of each of the great vessels, and it speaks of experiments to test their validity.
"As we have noted, in connection with the tight ligature, that the artery above the bandage was distended and pulsated, not below it, so, in the case of the moderately tight bandage, on the contrary, do we find that the veins below, never above, the fillet swell and become dilated, while the arteries shrink; and such is the degree of distention of the veins here that it is only very strong pressure that will force the blood beyond the fillet and cause any of the veins in the upper part of the arm to rise.
Nor need the details of that interminable journey down the crowded artery of Broadway to the Centre of Things be entered into. An ignoble errand, Honora thought; and she sat very still, with flushed cheeks, in the corner of the carriage. Chiltern's finer feelings came to her rescue. He, too, resented this senseless demand of civilization as an indignity to their Olympian loves.
That battle might have ended in a disastrous defeat for the North but for the accident which deprived the Confederates of their commander. About the middle of the afternoon, while leading his men forward to the attack which was pressing the Federals back upon the river, he was struck by a bullet which severed an artery in the thigh.
It's very improbable that she'll regain consciousness." "But are you sure, doctor?" Rachel asked. The doctor answered grimly "No, I'm not I'm never sure. She may recover." "She's been rather disturbed this afternoon." The doctor lifted his shoulders. "That's got nothing to do with it," said he. "As I told you, she's had an embolus in one artery of the brain.
Kennedy had placed the apparatus on the laboratory table and then gently took the little dog from his basket and laid him beside it. A few minutes later the poor little suffering Buster was mercifully under the influence of an anesthetic. Quickly Craig worked. First he attached the end of one of the tubes by means of a little cannula to the carotid artery of the dog.
Americans willing to take their own cars, and willing to work, will find plenty to do in distributing such supplies over there. A request has come to me to find such Americans. Surgeons who can spare a scalpel, an artery clip or two, ligatures catgut or silk and forceps, may be certain of having them used at once.
But the arteries receive blood from the veins in no other way than by transmission through the heart, as we have already seen; so that if the aorta be tied at the base of the heart, and the carotid or any other artery be opened, no one will now be surprised to find it empty, and the veins only replete with blood.
The connection, however, is not a close one, and the artery when divided transversely is capable of retracting for a considerable distance within its sheath. In some of the larger arteries the sheath assumes the form of a definite membrane. The arteries are nourished by small vessels the vasa vasorum which ramify chiefly in the outer coat.
Not suspecting that the wound was dangerous, he continued to push forward, till he fell exhausted from loss of blood; when, on examining the hurt, it was found that the femoral artery had been cut; and before any proper assistance could be afforded, he literally bled to death.
