Paradoxical Respiration: during inspiration, the flail (abnormally mobile) segments of ribs are pulled inside the chest wall while during expiration the ribs are pushed out. Tuberculosis of the lung is a common disease in certain parts of the world. A complete course of treatment must be taken under the guidance of a physician.
Segments for the left and right lung are shown in the table. [5] The segmental anatomy is useful clinically for localising disease processes in the lungs. [5] A segment is a discrete unit that can be surgically removed without seriously affecting surrounding tissue. [9]
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 lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
The ventilation/perfusion ratio (V/Q ratio) is higher in zone #1 (the apex of lung) when a person is standing than it is in zone #3 (the base of lung) because perfusion is nearly absent. However, ventilation and perfusion are highest in base of the lung, resulting in a comparatively lower V/Q ratio.
Polymicrobial lung abscesses are usually due to aspiration and are located in the posterior segments of the upper lobes or superior segments of the lower lobes. [2] Klebsiella pneumoniae is a common cause of lung abscesses and is usually monomicrobial (caused by a single species of bacteria). Risk factors include diabetes and chronic lung ...

The thorax (pl.: thoraces or thoraxes) [1] or chest is a part of the anatomy of mammals and other tetrapod animals located between the neck and the abdomen. [2] [3]In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the body, each in turn composed of multiple segments.
