It has been estimated that more than 70% of the bacterial species on body surfaces cannot be cultured by standard culture techniques,[sup], traditional culture-based studies have described the bronchial tree
as sterile in healthy individuals,[sup], and only low-load colonizing potentially pathogenic microorganisms (PPMs) can be found during diseases.
Aspirated objects were removed from the following locations; right bronchial tree
(44%, n=37), left bronchial tree
Vergnon, "41 Years into the bronchial tree
: a very obstructive cap," The Clinical Respiratory Journal, 2016.
Furthermore, as the airway resistance decreases progressively in distal areas, inflammation is observed in the entire bronchial tree
in bronchial asthma , and inflammation of the distal airways is not reflected in respiratory function , we consider that inflammation of this part of physiologic stenosis to be the primary pathology of asthma.
In one case, a 9-year-old child was misdiagnosed as having asthma, which stemmed from symptoms secondary to stagnation of a tack in the bronchial tree
for several years .
He had an oesophagogram which showed contrast extravasation into the tracheo bronchial tree
 The spitting of blood derived from the lungs or bronchial tree
owing to pulmonary or bronchial hemorrhage is defined as hemotypsis.
The cough sensitive receptors are located in the bronchial tree
, particularly in the junction of the trachea which can be stimulated mechanically or chemically e.g.
Abnormal budding of the resultant bronchial tree
results in a bronchogenic cyst.
There is a consensus that the anatomical structure of the right main bronchus and branches of the bronchial tree
make it more susceptible to foreign body aspiration (9).
Multiple tortuous systemic arteries were seen along the right bronchial tree
. Irregular pleural thickening and intercostal collaterals were also seen on the right side [Figure 5, red arrow].
He said Mrs Preston contracted a condition called aspiration pneumonia, which develops due to the entrance of foreign materials into the bronchial tree
, or "food and drink going down the wrong way".
Another area of potential concern regarding inhaled insulin is the possible effect on the tissues that it comes in contact with on its way to the alveoli, including the linings of the mouth, throat, tongue, cheeks, gums, tonsils, trachea, bronchial tree
, vocal cords, larynx, nasal air sinuses, and olfactory mucosa (which has a direct connection to the brain).
Examples include the sliding interface between the lung and the chest, and structural impact of bronchial tree
in the lungs.
