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 bronchi are conducting passages for air into the lungs. A bronchus (/ ˈbrɒŋkəs / BRONG-kəs; pl.: bronchi, / ˈbrɒŋkaɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs. The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main ...
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 ...
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 ]
There is still much debate to whether pulmonary sequestration is a congenital problem or acquired through recurrent pulmonary infection. It is widely believed that extralobar pulmonary sequestrations are a result of prenatal pulmonary malformation while intralobar pulmonary sequestrations can develop due to recurrent pulmonary infections in adolescents and young adults.
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 ...
Infectious disease, respirology. Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) [1] containing necrotic debris or fluid caused by microbial infection. This pus -filled cavity is often caused by aspiration, which may occur during anesthesia, sedation, or unconsciousness from injury.
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]
