The bronchial tubes are tree-like branches of the windpipe, and extend to the lungs, which are extremely elastic and, upon being filled with air, become inflated and expand somewhat like a balloon.
Tredegar's departure Wyant was setting this forth at great length to Justine. Bessy had had a bad morning: the bronchial symptoms which had developed a day or two before had greatly increased her distress, and there had been, at dawn, a moment of weakness when it seemed that some pitiful power was about to defeat the relentless efforts of science. But Wyant had fought off the peril.
He looked convincingly at Mrs. Maynard, who said she should like to try it. "It's just bronchial with me, you know. But I should like to try it. I know it would be soothing; and I've always heard that whiskey was the very thing to build you up. But," she added, lapsing from this vision of recovery, "I couldn't take it unless Grace said so. She'd be sure to find it out."
The hammer fell on an empty chamber, rose and fell half a dozen times without educing any response other than the click of metal against metal: demonstrating beyond question that the revolver was unloaded. From the hand of the marauder another tongue of flame licked out, to the sound of the same dull, bronchial cough; and a bullet thumped heavily into the wall beside P. Sybarite.
If the prevailing symptoms have led our attention to the lungs, we find inflammation of the bronchial passages, or, in a few instances, of the substance of the lungs, or the submucous tissue of the cells. We rarely have inflammation of the pulmonary pleura, and never to any extent of the intercostal pleura. In a few lingering cases, tubercles and vomicae of the lungs have been found.
Again, these air passages have elastic fibers running the length of the tubes, which allow them to stretch and bend readily with the movements of the neck. The Cilia of the Air Passages. The inner surfaces of the windpipe and bronchial tubes are lined with mucous membrane, continuous with that of the throat, the mouth, and the nostrils, the secretion from which serves to keep the parts moist.
At the first halt a number lit up cigarettes, and as soon as they started a chorus of coughs showed where the seductive weed was getting in its deadly work on the lungs and bronchial tubes. The Commanding Officers passed the word along to try and not smoke, and not to use the water bottles, and the men did their best for the rest of the march.
The anterior opening is closed by the epiglottis. Just within is a V-shaped opening that is limited laterally by the folds of the laryngeal mucous membrane, the vocal chords. The trachea is a cylindrical tube originating at the posterior extremity of the larynx, and terminating within the chest cavity at a point just above the heart in the right and left bronchial tubes.
It is unquestionable that the Limnophysalis hyalina enter into the blood either by the bronchial mucous membrane, by the surface of the pulmonary vesicles, or by the mucous membrane of the intestinal canal, most often, no doubt, by the last, with the ingested water; this introduction is aided by the force of suction and pressure, which facilitates their absorption.
It is formed by a series of cartilaginous rings joined together at their borders by ligaments and lined by a mucous membrane. The bronchial tubes resemble the trachea in structure.
