The areas of the lungs that can be listened to using a stethoscope are called the lung fields, and these are the posterior, lateral, and anterior lung fields. The posterior fields can be listened to from the back and include: the lower lobes (taking up three quarters of the posterior fields); the anterior fields taking up the other quarter; and ...

Fig. 15 The arrangement of the air sacs and lungs in birds Fig. 16 The anatomy of bird's respiratory system, showing the relationships of the trachea, primary and intra-pulmonary bronchi, the dorso- and ventro-bronchi, with the parabronchi running between the two. The posterior and anterior air sacs are also indicated, but not to scale.
Pulmonology (/ ˌ p ʌ l m ə ˈ n ɒ l ə dʒ i /, / ˌ p ʊ l m ə ˈ n ɒ l ə dʒ i /, from Latin pulmō, -ōnis "lung" and the Greek suffix -λογία-logía "study of"), pneumology (/ n ʊ ˈ m ɒ l ə dʒ i, n j ʊ-/, built on Greek πνεύμων pneúmōn "lung") or pneumonology [1] (/ n ʊ m ə n ˈ ɒ l ə dʒ i, n j ʊ-/) is a medical specialty that deals with diseases involving ...
Hippocrates developed the view that the liver and spleen produced blood, and that this traveled to the heart to be cooled by the lungs that surrounded it. [19] He described the heart as having two ventricles connected by an interventricular septum, and depicted the heart as the nexus point of all of the vessels of the body.
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.
This can push the lung upwards, resulting in "blunting" of the costophrenic angle. The posterior angle is the deepest. Obtuse angulation is sign of disease. Chest x-ray is the first test done to confirm an excess of pleural fluid. The lateral upright chest x-ray should be examined when a pleural effusion is suspected.
