Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2]
For these purposes, hepatocytes are usually isolated from animal or human [8] whole liver or liver tissue by collagenase digestion, which is a two-step process. In the first step, the liver is placed in an isotonic solution, in which calcium is removed to disrupt cell-cell tight junctions by the use of a calcium chelating agent .
Albumin, carries thyroid hormones and other hormones, particularly fat soluble ones, fatty acids to the liver, unconjugated bilirubin, many drugs and Ca 2+ Ceruloplasmin, carries copper; Transcortin, carries cortisol, aldosterone and progesterone; Haptoglobin, carries free hemoglobin released from erythrocytes
Your liver works around the clock to detoxify and protect the body from harmful substances. Here are 7 foods that help promote the health of your liver.
The liver of mammals, fowl, and fish is commonly eaten as food by humans (see offal). Pork , lamb , veal , beef , chicken, goose , and cod livers are widely available from butchers and supermarkets while stingray and burbot livers are common in some European countries.
Liver sausages, such as Braunschweiger and liverwurst, are also a valued meal. Liver sausages may also be used as spreads. A traditional South African delicacy, skilpadjies, is made of minced lamb's liver wrapped in netvet (caul fat), and grilled over an open fire. Traditionally, some fish livers were valued as food, especially the stingray liver.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .
Gut bacteria, bacterial endotoxins, and microbial debris transported to the liver from the gastrointestinal tract via the portal vein will first come in contact with Kupffer cells, the first immune cells in the liver. It is because of this that any change to Kupffer cell functions can be connected to various liver diseases such as alcoholic ...
