| pulmonary hypostasis | Hydrostatic congestion of the lung. (05 Mar 2000) |
|---|---|
| pulmonary incompetence | Defective closure of the pulmonic valve permitting regurgitation into the right ventricle during diastole. (05 Mar 2000) |
| pulmonary insufficiency | Pulmonary here refers to the valve between the right ventricle of the heart and the pulmonary artery. If this valve is insufficient (incompetant) in its performance, blood sloshes back from the pulmonary artery into the right ventricle. (12 Dec 1998) |
| pulmonary ligament | <anatomy> Two-layered fold formed as the pleura of the mediastinum is reflected onto the lung inferior to the root of the lung. Synonym: ligamentum pulmonale, ligamentum latum pulmonis, Teutleben's ligament. (05 Mar 2000) |
| pulmonary lymph nodes | Small nodes that occur along the bronchi within the lung; they receive the drainage from localised areas of the lung and send efferents to bronchopulmonary nodes. Synonym: nodi lymphatici pulmonales. (05 Mar 2000) |
| pulmonary murmur | A murmur produced at the pulmonary orifice of the heart, either obstructive or regurgitant. (05 Mar 2000) |
| pulmonary oedema | <cardiology> A severe state of increased interstitial fluid within the lung that leads to flooding of the alveoli with fluid. This results in a severe disturbance of gas exchange across the alveolar surface. Often results from the ineffective pump function of the heart (noncardiac causes also exist). (27 Sep 1997) |
| pulmonary orifice | The opening of the pulmonary trunk from the right ventricle, guarded by the pulmonary valve. Synonym: ostium trunci pulmonalis, pulmonary orifice. (05 Mar 2000) |
| pulmonary osteoarthropathy | hypertrophic pulmonary osteoarthropathy |
| pulmonary pleura | The layer investing the lungs and dipping into the fissures between the several lobes. Synonym: pleura pulmonalis, pleura visceralis, pulmonary pleura. (05 Mar 2000) |
| pulmonary pleurisy | Inflammation of the pleura covering the lungs. Synonym: visceral pleurisy. (05 Mar 2000) |
| pulmonary plexus | One of two autonomic plexus's, anterior and posterior, at the hilus of each lung, formed by cardiopulmonary splanchnic nerves of the sympathetic trunk and bronchial branches of the vagus nerve; from them various branches accompany the bronchi and arteries into the lung. Synonym: plexus pulmonalis. (05 Mar 2000) |
| pulmonary pressure | The blood pressure in the pulmonary artery. (05 Mar 2000) |
| pulmonary ridges | A pair of ridge's overlying the common cardinal veins and bulging from the lateral body wall into the embryonic celom; so called because they give early indication of where the pleuropericardial folds will develop. (05 Mar 2000) |
| pulmonary sarcoidosis | <radiology> Stage, I hilar/mediastinal lymph nodes, II nodes and lung disease, III lung disease only, upper lobe predominance, superinfection with Aspergillus (investigate with thin-cut CT) See: sarcoidosis (12 Dec 1998) |
