| eustachian valve | An endocardial fold extending from the anterior inferior margin of the inferior vena cava to the anterior part of the limbus fossa ovalis. Synonym: valvula venae cavae inferioris, caval valve, eustachian valve, sylvian valve. (05 Mar 2000) |

| Krause's valve | A small fold in the interior of the lacrimal sac at its junction with the lacrimal duct. Synonym: Krause's valve. (05 Mar 2000) |
| floppy valve syndrome | <syndrome> Retrograde slippage of degenerating mitral or tricuspid valve leaflets into the valve's orifice beyond the point of closure during systole of the left ventricle; a feature of Barlow's syndrome. (05 Mar 2000) |
| frenulum of ileocaecal valve | A fold, more evident in cadavers, running from the junction of the two commissures of the ileocaecal valve on either side along the inner wall of the caecocolic junction. Synonym: frenulum valvae ileocaecalis, frenulum of Morgagni, Morgagni's frenum, Morgagni's retinaculum. (05 Mar 2000) |
| left atrioventricular valve | <anatomy, cardiology> The heart valve that divides the left atrium and left ventricle. During left atrial contraction, the mitral valve opens to allow blood to flow into the left ventricle. Upon closure, the mitral valve prohibits the regurgitation of blood back into the left atrium. The mitral valve is the only heart valve that has only 2 valve cusps (all others have 3). (13 Nov 1997) |
| lunula of semilunar valve | The free border of a semilunar valve at each side of the nodulus valvulae semilunaris. Synonym: lunula valvulae semilunaris. (05 Mar 2000) |
| acute pulmonary alveolitis | Acute inflammation involving exudate into the pulmonary alveoli and impaired gas exchange; may result in necrosis with haemorrhage into the lungs; occurs in Goodpasture's syndrome, in association with a glomerulonephritis. (05 Mar 2000) |
| acute pulmonary eosinophilia | <chest medicine> A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| adenomatosis, pulmonary | A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells. It is characterised by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (12 Dec 1998) |
| apical branch of inferior lobar branch of right pulmonary artery | <anatomy, artery> Branch (of the inferior lobar branch) of the right pulmonary artery serving the apical segment of the inferior lobe of the right lung. Synonym: ramus apicalis lobi inferioris arteriae pulmonalis dextrae. (05 Mar 2000) |
| apicoposterior branch of left superior pulmonary vein | <anatomy, vein> Drains apicoposterior bronchopulmonary segment of superior lobe of left lung. Synonym: ramus apicoposterior venae pulmonalis sinistrae superioris. (05 Mar 2000) |
| basal part of pulmonary artery | <anatomy, artery> See: right pulmonary artery, left pulmonary artery. (05 Mar 2000) |
| vein, pulmonary | 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) |
| medial basal branch of pulmonary artery | <anatomy, artery> A branch of the basal part of inferior lobar branches of the left and right pulmonary arteries. Synonym: ramus basalis medialis. (05 Mar 2000) |
| resistance, pulmonary | The opposition of the respiratory tree to air flow. (12 Dec 1998) |
