| transplant lung syndrome | <syndrome> A syndrome associated with fever and diffuse bilateral pulmonary infiltration mainly at the base or at the hilum of the lung; can accompany rejection of an organ (kidney) transplant or follow a reduction in dosage of an immunosuppressive drug. (05 Mar 2000) |
| transverse fissure of the lung | The deep fissure that separates the upper and middle lobes of the right lung. Synonym: fissura horizontalis pulmonis dextri, horizontal fissure of right lung, minor fissure. (05 Mar 2000) |

| eosinophilic lung disease | <radiology> Idiopathic: Loeffler pneumonia, chronic eosinophilic pneumonia, hypereosinophilic syndrome, specific: drugs (e.g., nitrofurantoin), parasites, fungi (ABPA, bronchocentric granulomatosis), vasculitis / granulomatosis: Wegener's granulomatosis, polyarteritis nodosa, sarcoidal angiitis (12 Dec 1998) |
| extravascular lung water | <physiology> Water present within the lungs; its volume is roughly equal to, or a little less than, the intracellular blood volume of the lungs. Accumulations of extravascular lung water result in pulmonary oedema. (12 Dec 1998) |

| folded-lung syndrome | <syndrome> Collapse of part of the lung caught between shrinking fibrous pleura scars, sometimes resulting from pleural asbestosis. Synonym: round atelectasis. (05 Mar 2000) |
| lung | <anatomy> An organ for aerial respiration; commonly in the plural. "My lungs began to crow like chanticleer." (Shak) In all air-breathing vertebrates the lungs are developed from the ventral wall of the oesophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive saclike character, but in the higher forms the connection with the oesophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax. See Respiration. <medicine> Lung fever, pneumonia. <botany> Lung flower, one of the breathing organs of spiders and snails. Origin: OE. Lunge, AS. Lunge, pl. Lungen; akin to D. Long, G. Lunge, Icel. & Sw. Lunga, Dan. Lunge, all prob. From the root of E. Light. See Light not heavy. Source: Websters Dictionary (01 Mar 1998) |
| lung abscess | A collection of pus within a cavity in the lung due to a bacterial infection (bacterial endocarditis). Certain bacteria (Staphylococcus, Pseudomonas, Tuberculosis, Klebsiella) are more likely to cavitate the lung and cause abscess formation. (27 Sep 1997) |
| lung bud | The endodermal lung primordium which will give rise to the epithelial lining of the respiratory tract. Synonym: lung bud. (05 Mar 2000) |
