| pulmonary surfactants | Lipoproteins in which the lipid moiety is based mainly on lecithin and other phospholipids. They may also contain small amounts of prostaglandins and other compounds. Composition is species dependent. They are secreted by the mitochondria of type II alveolar cells. Surfactants regulate the surface tension of the mucoid layer lining the alveoli. Absence of the surfactants in premature infants results in hyaline membrane disease and in adults in atelectasis. Synthetic pulmonary surfactants have also been prepared and are used therapeutically.

| pulmonary surgical procedures | Surgery performed on the lung. (12 Dec 1998) |
| pulmonary transpiration | The passage of water vapor from the blood into the air via the respiratory tract. (05 Mar 2000) |
| pulmonary trunk | Origin, right ventricle of heart; distribution, it divides into the right pulmonary artery and the left pulmonary artery, which enter the corresponding lungs and branch along with the segmental bronchi. Synonym: truncus pulmonalis, arteria pulmonalis, pulmonary artery, venous artery. (05 Mar 2000) |
| pulmonary tuberculosis | Tuberculosis of the lungs. (05 Mar 2000) |
| pulmonary tularaemia | Tularaemia affecting the lungs; tularaemic pneumonia. Synonym: pulmonic tularaemia. (05 Mar 2000) |
| pulmonary valve | <anatomy, cardiology> The heart valve that divides the right ventricle and the pulmonary artery. The pulmonic valve opens when the right ventricle contracts allowing blood to flow into the pulmonary artery. The pulmonic valve on closure prohibits the backwash of unoxygenated blood into the right ventricle. The pulmonic valve has 3 valve cusps. (27 Sep 1997) |
| pulmonary valve insufficiency | Backflow of blood from the pulmonary artery into the right ventricle, owing to imperfect functioning of the pulmonary valve. (12 Dec 1998) |
| pulmonary vein | <anatomy, vein> One of four vessels that carry aerated blood from the lungs to the right atrium of the heart. (the four are the right and left superior and inferior pulmonary veins). The pulmonary veins are the only veins that carry bright red oxygenated blood. (12 Dec 1998) |
| pulmonary veins | The veins that return the oxygenated blood from the lungs to the left atrium of the heart. (12 Dec 1998) |
| pulmonary venolobar syndrome | <radiology> Always involves aplasia of one or more lobes of right lung, variably involves: partial anomalous pulmonary venous return (scimitar-shaped vein), usually drains to IVC; but portal vein, hepatic vein, RA possible, absent or small pulmonary artery perfusing abnormal lung segment, arterial supply from thoracic/abdominal aorta or coeliac axis, anomalies of hemidiaphragm on affected side, anomalies of bony thorax or thoracic soft tissues Synonym: scimitar syndrome (12 Dec 1998) |
| pulmonary veno-occlusive disease | Obstruction of the small- and medium-sized pulmonary veins by fibrous proliferation of the intima and media or by thrombosis or a combination of both. (12 Dec 1998) |
| pulmonary ventilation | The process of exchange of air between the lungs and the ambient air. Pulmonary ventilation is a measure of the rate of ventilation expressed usually in liters per minute. (12 Dec 1998) |
| pulmonary wedge pressure | The blood pressure as recorded after wedging a catheter in a small pulmonary artery; believed to reflect the pressure in the pulmonary capillaries. (12 Dec 1998) |
| simple pulmonary eosinophilia | Pulmonary infiltrates seen as transient migratory shadows on the chest X-ray, accompanied by blood eosinophilia; often symptomless, but there may be cough, fever, and breathlessness; most cases are due to worm infestation, especially by Ascaris lumbricoides; a few cases follow administration of drugs. Synonym: Loffler's syndrome. (05 Mar 2000) |
