Irregularly arranged plates of hyaline cartilage surround the smooth muscle. These plates give structural support to the bronchus and maintain the patency of the lumen.

This branch supplies the superior lobe of the right lung and is the most superior of all secondary bronchi. It arises above the level of the pulmonary artery , and for this reason is named the eparterial bronchus . All other distributions falling below the pulmonary artery are termed hyparterial. This classification is attributed to Christoph Theodor Aeby 1835 1885 and is central to his model of the anatomical lung which he presented in a monograph titled, Der Bronchialbaum der S ugethiere und des Menschen, nebst Bemerkungen ber den Bronchialbaum der V gel und Reptilien Leipzig Wilhelm Engelmann, 1880 .

The azygos vein arches over it from behind and the right pulmonary artery lies at first below and then in front of it. About 2 cm. from its commencement it gives off a branch to the upper lobe of the right lung. This is termed the eparterial branch of the bronchus, because it arises above the right pulmonary artery . The bronchus now passes below the artery, and is known as the hyparterial branch it divides into two branches for the middle and lower lobes. If a foreign body in the airway passes through the trachea, it will most likely enter the right main bronchus instead of the left, due to the straighter alignment of the right bronchus to the trachea.

Mucociliary clearance , also referred to as mucociliary apparatus or mucociliar clearance MCC , derived from mucus , Cilium cilia cilia of the tracheal surface epithelium in the respiratory tract and clearance describes the self clearing mechanism of the Bronchus bronchi . The Bronchus main bronchi down to the Bronchus alveoli are lined with a respiratory epithelium . On that, cilium is present, bearing hair shaped structures on its surface cilia . The Cilium cilia are surrounded by a thin fluid film of mucus. On top of that is a second viscous film of mucus, in which foreign particles and microorganisms get stuck. Within the thin fluid film of mucus the cilia act out movements coordinated in direction towards the pharynx . Thereby the viscous film of mucus including its freight is transported off in direction towards the mouth, where it is either swallowed or expelled via coughing. Important for good mucociliary clearance are the number of cilia, their structure, activity, and coordinated movement. Optimum functionality of mucociliary clearance presuppose a temperature of 37 C and an Humidity absolute humidity of 44 mg dm corresponding to a Humidity relative humidity of 100 . Under the condition of insufficient temperature and humidity, after a short time the ciliary cells suspend their transport function. Under such circumstances, bacterial germinal colonization is facilitated. Pulmonary infections and damaging of the pulmonic tissues may be the consequence. High humidity enhances the functionality of the mucociliary clearance. Two methods of supporting mucociliary clearance are the active and the passive respiratory gas humidification , which in particular are applied in mechanical ventilation .

mergeto Bronchiole date November 2009 The primary bronchioles arise from the tertiary bronchus tertiary bronchi . They are histologically distinct from the tertiary bronchi in that their walls do not have hyaline cartilage and they have Clara cell s in their epithelial lining. The epithelium starts as a simple columnar epithelium simple ciliated columnar epithelium and changes to simple cuboidal epithelium simple ciliated cuboidal epithelium as the primary bronchiole decreases in size. The diameter of the primary bronchioles is often said to be less than 1 mm, though this value can actually range from 5 mm to 0.3 mm. As stated, these bronchioles do not have hyaline cartilage to maintain their patency. Instead, they rely on elastic fiber s attached to the surrounding human lung lung tissue for support. The inner lining lamina propria of these bronchioles is thin with no glands present, and is surrounded by a layer of smooth muscle . As the primary bronchioles get smaller they divide into terminal bronchiole s. References Dudek, Ronald W. High Yield Histology , 3rd ed. 2004 . ISBN 0 7817 4763 5 Gartner, Leslie P. and James L.
