| liver acinus | The smallest functional unit of the liver, comprising all of the liver parenchyma supplied by a terminal branch of the portal vein and hepatic artery; typically involves segments of two lobules lying between two terminal hepatic venules. Synonym: Rappaport's acinus. (05 Mar 2000) |
|---|---|
| liver anatomy | <radiology> Main lobar fissure: plane connecting gall bladder bed and IVC (Cantlie line), middle hepatic vein runs here, divides right and left lobes, right hepatic vein: divides anterior and posterior segments of the, right lobe, falciform ligament: divides medial and lateral segments of the left lobe, contains ligmentum teres, caudate lobe: bounded posteriorly by fossa of IVC and anteriorly by the, fissure of the ligamentum venosum (12 Dec 1998) |
| liver, artificial | Devices for simulating the activities of the liver. They often consist of a hybrid between both biological and artificial materials. (12 Dec 1998) |
| liver breath | A peculiar odour to the breath in persons with severe liver disease; caused by volatile aromatic substances that accumulate in the blood and urine due to defective hepatic metabolism. Synonym: liver breath. (05 Mar 2000) |
| liver bud | The primordial cellular diverticulum of the embryonic foregut endoderm that gives rise to the parenchyma of the liver. (05 Mar 2000) |
| liver calcifications | <radiology> TB / histoplasmosis, chronic granulomatous disease of childhood (CGD), echinococcal (hydatid) cyst, portal vein thrombosis, metastatic adenocarcinoma, giant haemangioma, hepatoblastoma (12 Dec 1998) |
| liver cancer | <oncology, tumour> A tumour of the liver. most cancer involving the liver is spread (metastatic) from other areas (colon, breast or lung). See: hepatoma. (27 Sep 1997) |
| liver cell | Usually implies hepatocytes, even though other cell types are found in the liver Kupffer cells for example). Hepatocytes are relatively unspecialised epithelial cells and are the biochemist's typical animal cell. (18 Nov 1997) |

| liver circulation | The circulation of blood through the vessels of the liver. (12 Dec 1998) |
| liver cirrhosis | Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules. (12 Dec 1998) |
| liver cirrhosis, alcoholic | Liver cirrhosis in alcoholics. (12 Dec 1998) |
| liver cirrhosis, biliary | Liver cirrhosis in which there is interference with intrahepatic bile flow. It includes primary biliary cirrhosis, an intrahepatic disturbance of bile secretion affecting predominantly middle-aged women and with segmental destruction and, later, absence of septal bile ducts (cirrhosis is the end stage); and secondary biliary cirrhosis, which is produced by prolonged mechanical obstruction of large intrahepatic or extrahepatic bile ducts. (12 Dec 1998) |
| liver cyst | <radiology> Simple cyst, polycystic liver disease (50% most likely to be renal cysts), abscess (pyogenic, amebic, hydatid), traumatic haematoma, Caroli disease, cystic hepatoblastoma, cystadenoma / cystadenocarcinoma, haemangioendothelioma, cystic metastasis (uncommon): sarcoma, melanoma, ovarian cystadenocarcinoma (12 Dec 1998) |
