| bronchial veins | Many veins running in front of and behind the bronchi and uniting into two main trunks which empty on the right side into the azygos vein, on the left into the accessory hemiazygos or the left superior intercostal vein. Synonym: venae bronchiales. (05 Mar 2000) |

| bronchial voice | A modification of the voice sounds, by which they are intensified and heightened in pitch; observed in auscultation of the chest in certain cases of intro-thoracic disease. Origin: Gr. Windpipe + sound. Source: Websters Dictionary (01 Mar 1998) |
| bronchic | <anatomy> Bronchial. Source: Websters Dictionary (01 Mar 1998) |
| bronchic cells | One of the thin-walled saclike terminal dilations of the respiratory bronchioles, alveolar ducts, and alveolar sacs across which gas exchange occurs between alveolar air and the pulmonary capillaries. Synonym: alveoli pulmonis, alveolus, air cells, air vesicles, bronchic cells. (05 Mar 2000) |
| bronchiectasia | Synonym: bronchiectasis. (05 Mar 2000) |
| bronchiectasia sicca | Bronchiectasis characterised by lack of productive cough and by occasional haemoptysis. Synonym: bronchiectasia sicca. (05 Mar 2000) |
| bronchiectasis | <chest medicine> Persistent and progressive dilation of bronchi or bronchioles as a consequence of inflammatory disease (lung infections), obstruction (tumour) or congenital abnormality (for example cystic fibrosis). Symptoms include fetid breath and paroxysmal coughing, with the expectoration of mucopurulent matter. It may affect the bronchioles uniformly (cylindric bronchiectasis) or occur in irregular pockets (sacculated bronchiectasis) or the dilated bronchi may have terminal bulbous enlargements (fusiform bronchiectasis). Although rarely congenital, it is most often an acquired condition in childhood. (13 Nov 1997) |
| bronchiectatic | Relating to bronchiectasis. (05 Mar 2000) |
| bronchiloquy | Rarely used term for bronchophony [bronchi-+ L. Loquor, to speak (05 Mar 2000) |
| bronchiogenic | <anatomy> Originating from the bronchi. Examples include bronchogenic carcinoma (cancer). Origin: Gr. Gennan = to produce (27 Sep 1997) |
| bronchiolar adenocarcinoma | <tumour> A carcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent. Synonym: alveolar cell carcinoma, bronchiolar adenocarcinoma, bronchiolo-alveolar carcinoma, bronchioloalveolar adenocarcinoma. (05 Mar 2000) |

| bronchiolar exocrine cell | A rounded, club-shaped, nonciliated cell protruding between ciliated cell's in bronchiolar epithelium; believed to be secretory in function. Synonym: bronchiolar exocrine cell. (05 Mar 2000) |
| bronchiole | <anatomy> This refers to the smaller airways in the lungs. A minute subdivisions of the bronchi that terminate in the alveoli (oxygen exchange apparatus). (13 Nov 1997) |
| bronchiolectasia | Bronchiectasis involving the bronchioles. Synonym: bronchiolectasia. Origin: bronchiole + G. Ektasis, a stretching (05 Mar 2000) |
