Page 141 - ... depending upon certain states of the system, or upon the operation of external agents. 8. It appears, upon the whole, probable, that the atmospheric air is absorbed by the blood in its whole substance, and that certain proportions of each of its ingredients are discharged or retained according to the demands of the system. 9. We have no proof that hydrogen is discharged from the blood.7 § 5.
Page 451 - The latter tube enters just wbere the paunch, the second and third stomachs approach each other ; it is then continued with the groove, which ends in the third stomach. This groove is therefore open to the first stomachs, which lie to its right and left. But the thick prominent lips, which form the margin of the groove, admit of being drawn together so as to form a complete canal : which then constitutes a direct continuation of the oesophagus into the third stomach. The functions of this very singular...
Page 562 - Magendie and Delille performed a striking experiment, with the view of settling, if possible, the question of venous or lymphatic absorption of medicines and poisons. They divided all the parts of one of the posterior extremities of a dog, except the artery and vein, the former being left entire, for the purpose of preserving the life of the limb. A portion of the upas tieute was then applied to a wound in the foot : in the short space of four minutes the effects of the poison were evident, and in...

He conceives that what has been supposed to be the gastric juice, is, in fact, nothing but saliva; that it possesses no peculiar powers of acting on alimentary matter; that the principal use of the gastric juice is to dilute the food; and that the only action of the stomach consists in "une absorption vitale et elective...
Page 55 - Innumerable trains or tribes of other motions are associated with these muscular motions which are excited by irritation; as by the stimulus of the blood in the right chamber of the heart, the lungs are induced to expand themselves; and the pectoral and intercostal muscles, and the diaphragm, act at the same time by their associations with them.
Page 108 - I shall briefly recapitulate the result of our inquiry. 1. Air which has been respired loses a part of its oxygen ; the quantity varies considerably, not only in the different kinds of animals, but in different animals of the same species, and even in the same animal at different times, according to the operation of certain external agents, and of certain states of the constitution and functions. Upon an average we may assume that a man, under ordinary circumstances, consumes about 45000 cubic inches,...
Page 451 - ... into the third stomach. The functions of this very singular part will vary, according as we consider it in the state of a groove, or of a closed canal. In the first case, the grass, &c. is passed, after a very slight degree of mastication, into the paunch, as into a reservoir. Thence it goes in small portions into the second stomach, from which, after a further maceration, it is propelled, by a kind of antiperistaltic motion, into the oesophagus, and thus returns into the mouth.
