| bronchial breathing | Breath sounds of a harsh or blowing quality, heard on auscultation of the chest, made by air moving in the large bronchi and barely, if at all, modified by the intervening lung; duration of the expiratory sound is as long as or longer than that of the inspiratory sound, and its pitch as high as or higher than that of the inspiratory sound; may be heard over a consolidated lung, above a pleural effusion due to an underlying compressed lung, and rarely over a pulmonary cavity; whispered pectoriloquy is another manifestation that usually can be elicited when bronchial breathing is present.

| bronchial bud | One of the outgrowths from the primordial endodermal laryngotracheal tube giving rise to the primary bronchi. See: laryngotracheal diverticulum. (05 Mar 2000) |
| bronchial calculus | A hard concretion in a bronchus or bronchial tube. Synonym: bronchial calculus. Origin: broncho-+ G. Lithos, stone (05 Mar 2000) |
| bronchial fistula | An abnormal passage or communication between a bronchus and another part of the body. (12 Dec 1998) |
| bronchial glands | Mucous and seromucous glands whose secretory units lie outside the muscle of the bronchi. See: bronchopulmonary lymph nodes. (05 Mar 2000) |
| bronchial hyperreactivity | Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory. (12 Dec 1998) |
| bronchial pneumonia | <chest medicine> A name given to an inflammation of the lungs which usually begins in the terminal bronchioles. These become clogged with a mucopurulent exudate forming consolidated patches in adjacent lobules. The disease is frequently secondary in character, following infections of the upper respiratory tract, specific infectious fevers and debilitating diseases. In infants and debilitated persons of any age it may occur as a primary affection. Synonym: bronchial pneumonia, bronchoalveolitis, bronchopneumonitis, lobular pneumonia. (11 Jan 1998) |
| bronchial polyp | A polyp growing from the bronchial mucosa. (05 Mar 2000) |
| bronchial provocation tests | Tests involving inhalation of allergens (nebulised or in dust form), nebulised pharmacologically active solutions (e.g., histamine, methacholine), or control solutions, followed by assessment of respiratory function. These tests are used in the diagnosis of asthma. (12 Dec 1998) |
| bronchial respiration | A tubular blowing sound caused by the passage of air through a bronchus in an area of consolidated lung tissue. (05 Mar 2000) |
| bronchial spasm | Spasmodic contraction of the smooth muscle of the bronchi. (12 Dec 1998) |
| bronchial tubes | <anatomy> The bronchial tubes which arise from the branching of the trachea, especially. The subdivision of the bronchi. Origin: L, pl. Cf. Bronchus. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| trans-bronchial biopsy | <chest medicine, procedure> A biopsy that is performed through the wall of the bronchus (using the bronchoscope). This involves obtaining a small piece of lung tissue for microscopic analysis. This is a useful alternative to an open surgical biopsy, where an incision must be made. (17 Mar 1998) |
