Bronchopulmonary segments visible but not labeled. A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1][2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment.
The secondary bronchi divide further into tertiary bronchi, (also known as segmental bronchi), each of which supplies a bronchopulmonary segment. A bronchopulmonary segment is a division of a lung separated from the rest of the lung by a septum of connective tissue. This property allows a bronchopulmonary segment to be surgically removed ...
Each bronchopulmonary segment has its own (segmental) bronchus and arterial supply. [10] Segments for the left and right lung are shown in the table. [7] The segmental anatomy is useful clinically for localising disease processes in the lungs. [7] A segment is a discrete unit that can be surgically removed without seriously affecting ...
FMA. 265130. Anatomical terminology. [edit on Wikidata] The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. [1] The respiratory tract is lined with respiratory epithelium as respiratory mucosa. [2]
Bronchopneumonia is a subtype of pneumonia. It is the acute inflammation of the bronchi, accompanied by inflamed patches in the nearby lobules of the lungs. [ 1 ] It is often contrasted with lobar pneumonia; but, in clinical practice, the types are difficult to apply, as the patterns usually overlap. [ 2 ]
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production and/or exacerbations) due to abnormalities of the airways (bronchitis ...
These in turn give rise to tertiary bronchi (tertiary meaning "third"), known as segmental bronchi which supply each bronchopulmonary segment. [1] The segmentary bronchi subdivide into fourth order, fifth order and sixth order segmental bronchi before dividing into the bronchioles.
Bronchopulmonary dysplasia (BPD; part of the spectrum of chronic lung disease of infancy) is a chronic lung disease which affects premature infants. Premature (preterm) infants who require treatment with supplemental oxygen or require long-term oxygen are at a higher risk. [1] The alveoli that are present tend to not be mature enough to ...
