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.
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / 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 bronchus.
The unit described as the secondary pulmonary lobule is the lobule most referred to as the pulmonary lobule or respiratory lobule. [25]: 489 [31] This lobule is a discrete unit that is the smallest component of the lung that can be seen without aid. [29] The secondary pulmonary lobule is likely to be made up of between 30 and 50 primary lobules ...
This concept is generally attributed to an article by West et al. in 1964, [1] but was actually proposed two years earlier by Permutt et al. [2] In this article, Permutt suggests "The pressure in the pulmonary arteries and veins is less at the top than at the bottom of the lung. It is quite likely that there is a portion of the lung toward the ...
Primary cancers (e.g. bronchial carcinoma, mesothelioma) Secondary cancers (e.g. cancers that originated elsewhere in the body, but have seeded themselves in the lungs) Insufficient surfactant (e.g. respiratory distress syndrome in pre-term babies) . Disorders of the respiratory system are usually treated by a pulmonologist and respiratory ...
The carina of trachea (also: "tracheal carina" [1]) is a ridge [1] of cartilage [2] at the base of the trachea separating the openings of the left and right main bronchi. [ 1 ] [ 2 ] Structure
Donald Trump's election victory last week is already having an effect on global supply chains. While many firms are waiting to see what Trump's trade policies will be, some are planning ahead.
The bronchial circulation is the part of the systemic circulation that supplies nutrients and oxygen to the cells that constitute the lungs, as well as carrying waste products away from them. It is complementary to the pulmonary circulation that brings deoxygenated blood to the lungs and carries oxygenated blood away from them in order to ...
