Another worm about the same size was found in the left bronchia, and a still smaller one among the mucus of the trachea: there were also four others in the nose. Some years ago I found some worms of the filacia species in the right ventricle of the heart of a dog, which had produced sudden death by interrupting the action of the valves. The following is a curious case of tape-worm, by Mr.
Annandale saw a little patient who had swallowed a bead of glass, which had lodged in the bronchus. He introduced the handle of a scalpel into the trachea, producing sufficient irritation to provoke a brusque expiration, and at the second attempt the foreign body was expelled.
The continuation of the larynx is the trachea, a tube about three-fourths of an inch in diameter, and about four inches long. It extends downwards along the middle line of the neck, where it may readily be felt in front, below the Adam's apple. Larynx, Trachea, and the Bronchi.
From speech: Since not the least vocal sound flows forth from the mouth without the concurrent aid of the lungs, for the sound, which is articulated into words, all comes forth from the lungs through the trachea and epiglottis, therefore, according to the inflation of these bellows and the opening of the passage the voice is raised even to a shout, and according to their contraction it is lowered; and if the passage is entirely closed speech ceases and thought with it.
THE GLOTTIS AND VOCAL CORDS VIEWED FROM ABOVE 1, Glottis. 2, True Cords. 3, False Cords. 4, Epiglottis. 5, Base of Tongue. V, Ventricles. T, Thyroid Cartilage. C, Cricoid Cartilage. W, Windpipe or Trachea. The laryngoscope should not, in fact, leave the hands of the physician.
When the passions are in revolt, or danger approaches from without, then the heart beats and swells; and the creating powers, knowing this, implanted in the body the soft and bloodless substance of the lung, having a porous and springy nature like a sponge, and being kept cool by drink and air which enters through the trachea.
But it is conceivable that the now utterly lost branchiae might have been gradually worked in by natural selection for some distinct purpose: for instance, Landois has shown that the wings of insects are developed from the trachea; it is therefore highly probable that in this great class organs which once served for respiration have been actually converted into organs for flight.
Another source of difficulty is subglottic, owing to inflammation of the mucous membrane in the trachea, which extends upward and involves the cords. The inflammation, passing upward, may easily affect the voice. Such inflammation is discovered by a tickling sensation in the trachea, causing a dry, harsh cough about the third day after a cold has found lodgment "in the head," as the phrase goes.
The presence of vomited matters in the trachea and bronchi is a valuable sign of drowning. The blood collects in the venous system, and is dark and fluid. Tardieu's spots are not so frequently met with in cases of drowning as in other forms of asphyxia. The other signs of death by asphyxia are present. Wounds may be present on the body, due to falling on stakes, injuries from passing vessels, etc.
The science which treats of living bodies. A bag, or sac, serving as a receptacle of some secreted fluid, as the gall bladder, etc. The receptacle of the urine in man and other animals. Bright's Disease. A group of diseases of the kidney, first described by Dr. Bright, an English physician. The first two divisions, or branches, of the trachea; one enters each lung. Bronchial Tubes.
