cirrhosis liver (post-mortem), probable alcoholic cirrhosis. These features are a direct consequence of liver cells not functioning: Spider angiomata or spider nevi happen when there is dilatation of vasculature beneath the skin surface. [29] There is a central, red spot with reddish extensions that radiate outward.
The hepatocyte plates are one cell thick in mammals and two cells thick in the chicken. Sinusoids display a discontinuous, fenestrated endothelial cell lining. The endothelial cells have no basement membrane and are separated from the hepatocytes by the space of Disse, which drains lymph into the portal tract lymphatics. [citation needed]
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] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to ...
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 .
In the first trimester fetus, the liver is the main site of red blood cell production. By the 32nd week of gestation, the bone marrow has almost completely taken over that task. [56] The liver helps in the purification of blood. The Kupffer cells of liver are phagocytic cells that help in the phagocytosis of dead blood cells and bacteria from ...
Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself is produced by fusion of two gametes, each having been produced by meiotic cell division. [5] [6] After growth from the zygote to the adult, cell division by mitosis allows for continual construction and repair of the organism. [7]
The name is derived from the fact that the cells undergoing this form of cell death increase in size . It is generally considered a form of apoptosis , [ 1 ] and is a descriptor used in the context of inflamed fatty liver ( steatohepatitis ) [ 2 ] (which may be due to obesity or alcohol ), as well as viral hepatitis.
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [ 1 ] [ 2 ] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [ 3 ]
