Lunge

“ The Lungs take up the upper Region, and fill almost the whole Space, descending at the distance of two Fingers breadth from the Diaphragm; the Heart is situated in the middle, bearing its Point somewhat towards the Left side, under the Lobes of the Lungs, which are divided by the Mediastinum that distinguishes them into the Right and Left Parts. ”

“ Flying thus thou canst pause or advance without weariness. Like other men, thou wouldst fain be plunged forever in these spheres of light and perfume where now thou art, free of thy swooning body, and where thy thought alone has utterance. Fly! enjoy for a fleeting moment the wings thou shalt surely win when Love has grown so perfect in thee that thou hast no senses left; when thy whole being is all mind, all love. The higher thy flight the less canst thou see the abysses. There are none in heaven. ”

“ High above his birthplace the snowy Alps paint themselves against the sky, an aerial dream of beauty, softened by the tender hues of dawn and sunset, serenely fair through the rift of the tempest; even their white death takes a nameless grace from distance and atmosphere, clothing itself in beauty as a spirit in clay, and tempting wanderers to their graves: but no such beauty clothes the man whose daily vision beholds them; hard, clamorous, disputatious, with one hand he rends the rotten splendors of Rome from its tottering Image, and with the other plunges baby-souls to inevitable damnation ”

“ Do you love your enemy, Constantius, even if you do not smite him? Do you hate the lusts of the flesh or the alluring joys of this world, even if you do not, like a heated swimmer, plunge into their depths? Do you renounce the world, because you have not courage to make it your own? ”

“ In the aetiology of pulmonary affections, the relations between the lungs and the external air, and also between them and the circulatory system, are important. The lungs are, so to speak, placed between the right and left cavities of the heart, and the only way for the blood to pass from the right ventricle to the left side of the heart, except in cases of a patent foramen ovale or other congenital defect forming a communication between the two sides of the organ, is by passing through them. ”

“ The stays or girdle which braces the loins of most women prevents the expansion of the thoracic apparatus, naturally attained by the descent of the diaphragm; and hence, no doubt, the lung will distend inordinately above towards the neck. It is an interesting fact for those anatomists who study the higher generalizations of their science, that at those very localities—viz., the neck and loins, where the lungs by their own natural effort are prone to extend themselves in forced inspiration—happen the “anomalous” creations of cervical and lumbar ribs. ”

“ Roughly speaking, the lungs begin at the sterno-clavicular articulation above, the apex coming up above the level of the first rib, and extend downward together to the fourth cartilage, where the lower margins gradually separate, the lowest lung limit being the eleventh rib in the vertebral region. Each lung is conical. The apices extend upward and the bases, which are broad and concave, rest upon the diaphragm. The right lung is divided by a fissure into three lobes, the left into two. The root consists of a bronchus and pulmonary arteries, veins, lymphatics, and nerves. ”

“ Lungs consist of two long membranous bags, which run the whole length of the abdomen, anteriorly to the stomach and intestines; the opening of the larynx scarcely large enough to admit a pin's head; the lungs resemble two long air-bags, more than a true pulmonary apparatus; the cartilaginous laminæ of the branchia, three in number, attached superiorly to the integuments over the cervical vertebræ, converging together beneath or anteriorly, and are attached to a cartilage answering to the os hyoides ”

“ At birth the lungs are pinkish-white in color but in later life they are marked with slate-colored patches, due to the deposit in the lung tissue of particles of dirt breathed in. They are light, spongy, and highly elastic, and will float in water, crepitating upon pressure owing to the air in the tissue. ”

“ Thus, experiment has shown that in a foetus which has never breathed, the lungs are compact and will sink in water; but as soon as they become inflated with air, they spread over a larger surface, and are therefore more buoyant. Each lung is invested, as far as its root, with a membrane, called the pleura, which is then continuously extended to the cavity of the chest, thus performing the double office of lining it, and constituting a partition between the lungs. ”

“ The lung follows the heart. The whole mediastinum finds itself altered in its position and in its contents. The depressed diaphragm rises promptly to its old position in the pleural cavity. The liver, spleen, and the rib-wall undergo striking modifications. We do not expect the lung to dilate to its full extent, as after aspirations in simple pleurisies. The lung, indeed, is already impaired in its movement. We admit air in order to secure treatment to these surfaces. When air is admitted into the normal chest, the lung is retracted to about one-half its size. ”

“ Placing the ear against the ribs, upon various parts of the chest, we may learn with some practice to distinguish the progress of inflammation. In the healthy lung, the air passes in with a slight, rustling murmur, quite characteristic, and which, once heard, will always be recognized. ”

“ Added to which the lungs of a reptile are coarsely constructed, and composed of cells enormous in comparison with ours, so that the blood does not find nearly as many little chambers to rush into for a taste of air as with us. Moreover, you must understand that there is no such thing as a diaphragm here: the lungs float loosely in the form of elongated bags in the one only cavity of the body, and the slight movement of the ribs does not allow them to dilate sufficiently to take in much air at a time. ”

“ The lungs are a sort of air-sponges, and when you enlarge your chest to draw breath, they swell out with it, and suck the air in. On the other hand, you narrow your chest, and squeeze the lungs, and press the air from them;—that is breathing out. The lungs are made up of a lot of little cells. A small pipe—a little branch of the windpipe—opens into each cell. Two blood-vessels, a little tiny artery, and a vein to match, run into it also. The arteries bring into the little cells dark-colored blood, which has been all over the body. ”

“ The histological groundwork of the whole lung tissue is a connective tissue of fine elastic fibers. In the lungs, on the canal that appears as the elongation of the bronchus, cartilage appears, according to Rathke, as bands lying one behind the other ”

“ No organ is of greater importance to life than the lungs; and hence it is necessary not only to breathe a pure atmosphere, but also that we take in enough of it at every respiration to inflate the whole chest. The lungs may be said to commence with the soft lining of the trachea, and to extend in two huge lobes down into the chest ”

“ The same pores likewise appeared on the heart; which, in my opinion, are nothing but the extremities of the exhaling vessels. In removing the heart, I found the dorsal, and other lymphatic glands above the lungs, quite large, indurated, and of a dark greyish colour. Nothing remarkable appeared in the lungs; only, that the portion of the pleura, which invests the lungs, and is generally thin, was here thick and rough; and thro’ a glass it appeared as if covered with grains of sand; and might in several places have been easily torn from the lungs. ”

“ Secretion of the Lungs.—Like the lips and mouth, the lungs are invested on their free inner surface by a delicate mucous membrane, which constantly secretes a clear viscous fluid, the mucus. The lungs, therefore, like the nose, are always moist, and just as the nose is cleared by blowing it, so the lungs are cleared by hawking or coughing. A sense of discomfort or a feeling of irritation of the windpipe induces a deep inspiration, followed by an explosive expiration, which quickly brings up the mucus, so that it can be expectorated. ”

“ The bones surrounding the small, feeble lungs, now for the first time beginning to move, are so soft and pliable, that, under the slightest pressure, they will yield, and the capacity of the lungs be reduced. Yet I have seen the nurse [Pg 665] use the entire strength of her fingers in the first application of the skirt-bands. No thoughtful person, acquainted with the anatomy of the thorax in a new-born babe, can escape the conclusion that its vitality is seriously compromised by this pressure upon the principal organs of that vitality. ”

“ When air has to be admitted, its fibres tighten and bring it flat again, as you and your brother brought the handkerchief flat just now by tightening it.
The whole space previously occupied by the arch of the diaphragm is thus given up to the lungs, which, being elastic, instantly stretch themselves out to it; while air, running in through the nose and mouth, fills up in proportion the empty place (vacuum) created by the extension of the lungs, exactly as in the case of the bellows. ”

“ LUNGS
.—The lungs of a horse are two elastic lobes, consisting of air vessels, blood vessels, lymphatics, nerves, and cellular membranes, possessing conjunctively the properties of contraction and expansion; nearly filling three parts of what is termed the CHEST, and may, without much deviation from the line of professional consistency, be pronounced the very mainspring of existence. It is the good or bad state of the LUNGS upon which the duration of life becomes in a proportional degree dependent ”

“ The lungs follow the variations of capacity in the chest, expanding their air-cells when the latter is enlarged, and contracting when the chest is diminished. Thus, when the chest is expanded, the lungs follow, and consequently a vacuum is produced in their air-cells. The air then rushes through the mouth and nose into the trachea and its branches, and fills the vacuum as fast as it is made. ”

“ In the healthy adult male body, Plate 22, the two lungs, D D*, whilst in their ordinary expanded state, may be said to range over all that region of the trunk of the body which is marked by the sternal and asternal ribs. ”

“ The lungs are, among the internal organs, the most exposed to direct irritations, either by the air that constantly enters them and can irritate them, or by heterogeneous substances that it introduces, or especially by the changes of heat and cold that it occasions. 2d. These organs are connected by the most numerous sympathies with the other systems, the cutaneous, for example; so that perhaps, as it respects inflammation, a suppression of transpiration has as much influence upon the lungs alone, as upon all the other organs together. ”

“ People talk of ‘weak lungs,’ ‘weak chest,’ ‘weak throat,’ but perhaps it does not occur to everybody that strong lungs and strong throat are commonly to be had on the same terms as a strong arm or wrist—by exercise, training, use, work. ”

“ The texture of the lungs is very porous, and when inflated by blowing through the trachea, a quantity of air escapes, and fills the large and small apertures that surround them, as well as those of the sternum and ribs. ”
