What's the difference between bronchiole and trachea?

Bronchiole


Definition:

  • (n.) A minute bronchial tube.

Example Sentences:

  • (8) The consequence of these derangements is often widespread plugging of small bronchi and bronchioles.
  • (9) We therefore conclude that the clinical management of bronchiolitis requires close monitoring of body wt and plasma osmolality-urinary osmolality relationship; serum sodium levels may be misleading.

  • (12) The dendritic cells were initially described in lymphoid organs and have been recently shown in the normal human lung at the level of the bronchioles, preferentially in the peribronchiolar connective tissue and in the alveolar parenchyma.
  • (13) As the severity of the lesions increased so did the number of IgA-, IgG(Fc)- and in several cases non-immunoglobulin staining cells around the vasculature, bronchioles and in the alveolar septa.
  • (14) This case suggests that obstructive bronchiolitis with hypersensitivity pneumonitis is an etiologic factor of mediastinal emphysema.
  • (15) It was hypothesized that pathogenic Pasteurella spp and other microorganisms in nasal secretions transfer from the nasopharynx into the lungs by draining along the tracheal floor into ventral bronchi, bronchioles, and alveoli, and that pasteurella endotoxin, formed in infected lobules, thromboses and occludes lymphatics, capillaries, and veins and thereby causes ischemic necrosis.
  • (16) We studied 47 excised human lungs in order to examine the relationship between the number of alveolar attachments surrounding bronchioles 2 mm or less in diameter and the presence of small airways disease and overall lung function.
  • (17) Transbronchial biopsy revealed a lymphocytic bronchiolitis but no evidence of interstitial lung disease and a marked T-suppressor lymphocytosis was found on analysis of the bronchoalveolar lavage (BAL) specimen.
  • (18) Histamine hyperresponsiveness with viral bronchiolitis may depend on previous exposures to viruses or to other pathogens.
  • (19) None of the six ferritin-conjugated lectins showed higher binding in bronchioles compared to the bronchus, suggesting that a high level of surface oligosaccharides is not necessary for resistance to the metaplastic effects of HNE.
  • (20) Later alveolar septa between adjacent bronchioles became progressively thickened to produce lesions with similarities to human honeycombing.

Trachea


Definition:

  • (n.) The windpipe. See Illust. of Lung.
  • (n.) One of the respiratory tubes of insects and arachnids.
  • (n.) One of the large cells in woody tissue which have spiral, annular, or other markings, and are connected longitudinally so as to form continuous ducts.

Example Sentences:

  • (1) Aplasia of the trachea associated with multiple congenital anomalies is described in a stillborn male foetus with single umbilical artery.
  • (2) This was worsened by the right side compression of trachea end part, due to the abnormal left pulmonary artery as demonstrated by pulmonary angiography.
  • (3) Tracheal mucus transport rate (TMTR) and quantitative clearance of aerosolized Escherichia coli from the trachea, lung, and air sac were measured in healthy unanesthetized turkeys and in turkeys exposed by aerosol to a La Sota vaccine strain of Newcastle disease virus (NDV).
  • (4) Defects in the posterior one-half of the trachea, up to 5 rings long, were repaired, with minimal stenosis.
  • (5) Haemodynamic changes (supraventricular tachycardia, decreases in arterial pressure) were observed during laryngoscopy and intubation of the trachea in a patient receiving nifedipine and verapamil.
  • (6) General anaesthesia with apneic oxygenation may offer the ENT surgeon increased possibilities of exploration and operation at the level of the larynx and trachea, but owing to its biological consequences, it should be used only with circumspection and its indications should be totally justified, for acts of limited duration.
  • (7) Replacement of bath Na+ by choline decreased the PD of tracheas by 85% but did not change alveolar PD in the presence or absence of bumetanide.
  • (8) Compared to related compounds, N-nitrosobis(2-hydroxypropyl)amine and N-nitrosobis(2-acetoxy-propyl)amine which are also pancreatic carcinogens, BOP induced only a few neoplasms of the lung, liver, and kidney and none in the nasal cavity, larynx, and trachea.
  • (9) Experiments were conducted in a group of pigs to determine the ontogeny of antigen specific IgA in the trachea.
  • (10) Although they were born at different periods of the year, the calves in all three groups had similar bacterial loads in their noses and tracheas when they were 1 day old (P greater than 0.05).
  • (11) In one patient, a minitracheostomy tube perforated the posterior wall of the trachea, resulting in pneumomediastinum.
  • (12) The trachea and the bronchial tree (first through seventh order branches) both synthesized alpha1(II) chains.
  • (13) The respiratory functions of the oropharynx, larynx, and trachea of normal human fetuses in utero were explored by means of real-time, two-dimensional ultrasonography combined with color-flow and spectral Doppler analysis.
  • (14) The blood flow contributions and drainage patterns of the pulmonary and systemic circulations in the upper airways (trachea and main bronchi) were assessed in anesthetized dogs by injecting 15-micron radiolabeled microspheres into the right and left heart, respectively.
  • (15) There were no differences between boys and girls until age 14, when girls' tracheas stopped growing.
  • (16) The bronchi were involved more often than the trachea and the foreign body was located more frequently at the right bronchus (38 pt).
