bronchial tree,

an anatomic complex of the trachea and bronchi. The bronchi branch from the trachea. The right bronchus is wider and shorter than the left bronchus and branches into three secondary bronchi, one passing to each of the three lobes of the right lung. The left bronchus is smaller in diameter and about twice as long as the right bronchus. It is also more horizontal and more susceptible to obstruction. It branches into the secondary bronchi for the inferior and the superior lobes of the left lung. The bronchus is sometimes described as a bronchial tube.

tree [tre]

an anatomic structure with branches resembling a tree.

bronchial tree the bronchi and their branching structures; see color plates.

tracheobronchial tree the trachea, bronchi, and their branching structures; see color plates.

---

bronchial

pertaining to or affecting one or more bronchi.

---

bronchial calculus

a hard concretion formed in a bronchus by accretion about an inorganic nucleus or from calcified portions of lung tissue or adjacent lymph nodes.

bronchial edema

mucosal edema occurs in response to irritation and inflammation of tracheobronchial epithelium. Contributes to increased airway resistance.

feline bronchial asthma

a syndrome in cats characterized by acute episodes of coughing and dyspnea with wheezing. Usually recurrent and believed to be due to allergic reaction. Similar to allergic asthma in humans.

bronchial hypoplasia

swollen spongy tissue or cystic, lobulated tissue replaces lobes of normal lung tissue because of the impediment to air flow caused by dilated or collapsed hypoplastic bronchi; probably the basic defect in adenomatoid hamartoma or congenital adenomatoid malformation.

bronchial pattern

bronchi become more prominent in x-rays because they become more dense than surrounding air-filled lung tissue. Caused by peribronchial infiltration, fluid within the bronchus and calcification of the bronchial cartilage. Seen in chronic bronchitis and bronchiectasis.

bronchial spasm

bronchospasm.

bronchial tones

are the sounds made by the respired air as it passes through the larger air passages of normal lungs. They are best heard over the bifurcation of the trachea. They are harsher and louder than the vesicular murmur, the normal sounds produced in the parenchyma of the lung.

bronchial tree

the bronchi and their branching subdivisions.

bronchial tumors

see pulmonary neoplasm.
