bronchus: see lungslungs,
elastic organs used for breathing in vertebrate animals, excluding most fish, which use gills, and a few amphibian species that respire through the skin. The word is sometimes applied to the respiratory apparatus of lower animals.

bronchus [brong´kus] (pl. bron´chi) any of the larger passages conveying air to a lung (right or left principal bronchus) and within the lungs (lobar and segmental bronchi). See also respiration and see color plates.bron·chus, pl. bron·chi (brong'kŭs, brong'kī), [TA] One of two subdivisions of the trachea serving to convey air to and from the lungs. The trachea divides into right and left main bronchi, which in turn form lobar, segmental, and intrasegmental bronchi. Structurally, the intrapulmonary (secondary) bronchi have a lining of pseudostratified ciliated columnar epithelium and a lamina propria with abundant longitudinal networks of elastic fibers; there are spirally arranged bundles of smooth muscle, abundant mucoserous glands, and, in the outer part of the wall, irregular plates of hyaline cartilage. [Mod. L., fr. G. bronchos, windpipe] bronchus (brŏng′kəs)n. pl. bron·chi (-kī′, -kē′) Either of two main branches of the trachea, leading directly to the lungs.bronchus Any of the large airways of the lungs, beginning at the tracheal bifurcation, which gives rise to the the right and left mainstem (primary) bronchi; these divide into three lobar (secondary) bronchi in the right lung and two in the left, which then divide into segmental (tertiary) bronchi. The airway divisions after segmental bronchi are termed bronchioles. Bronchi have an outer fibrous layer with irregularly placed plates of hyaline cartilage, an interlacing network of smooth muscle and a mucous membrane lined by ciliated columnar epithelial cells and scattered mucus cells.bron·chus, pl. bronchi (brong'kŭs, -kī) One of the two subdivisions of the trachea serving to convey air to and from the lungs. The trachea divides into right and left main bronchi, which in turn form lobar, segmental, and subsegmental bronchi. The intrapulmonary bronchi have a lining of pseudostratified ciliated columnar epithelium and a lamina propria with abundant longitudinal networks of elastic fibers; there are spirally arranged bundles of smooth muscle, abundant mucoserous glands, and, in the outer part of the wall, irregular plates of hyaline cartilage. [Mod. L., fr. G. bronchos, windpipe] BRONCHEAL TREEbronchus (brong'kus) (brong'ki?, brong'ke?) plural.bronchi [Gr. bronchos, windpipe] One of the two large branches of the trachea. The trachea divides opposite the third thoracic vertebra into the right and left main bronchi. The point of division, called the carina trachea, is the site where foreign bodies too large to enter either bronchus would rest after passing through the trachea. The right bronchus is shorter and more vertical than the left one. After entering the lung each bronchus divides further and terminates in bronchioles. bronchus suisTracheal bronchus.tracheal bronchusAn accessory bronchus that branches off directly from the trachea, the carina, or another bronchus. It is an ectopic malformation of the respiratory tract that usually runs to the right upper lobe of the lung. Synonym: bronchus suis See: illustration; bronchibronchus A breathing tube. A branch of the windpipe (TRACHEA) or of another bronchus. The trachea divides into two main bronchi, one for each lung, and these, in turn, divide into further, smaller bronchi. See also BRONCHIOLES.bronchus one of a pair of tubes (bronchii) linking the trachea to the lungs in mammals. Each bronchus consists mainly of connective tissue and a small amount of smooth muscle, the tubes becoming finely divided into bronchioles within the lungs, forming a ‘bronchial tree’. See BREATHING and Fig. 81 . BronchusOne of the two large tubes connecting the windpipe and the lungs.Mentioned in: Lung Abscessbron·chus, pl. bronchi (brong'kŭs, -kī) One of two subdivisions of the trachea serving to convey air to and from the lungs.
