Hepatocyte nuclei are round with dispersed chromatin and prominent nucleoli. Anisokaryosis (or variation in the size of the nuclei) is common and often reflects tetraploidy and other degrees of polyploidy, a normal feature of 30-40% of hepatocytes in the adult human liver. [4] Binucleate cells are also common. [citation needed]
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 adult liver, most of the cells are binucleated, and most of the hepatocytes are tetraploid, which means that they have four times the amount of normal DNA. Their average lifespan is from approximately five months, and hepatocytes have a significant regeneration capacity after parenchymal loss by toxic processes, diseases or surgeries.
Its normal blood volume, including both that in the hepatic veins and that in the hepatic sinuses, is about 450 milliliters, or almost 10 percent of the body's total blood volume. When high pressure in the right atrium causes backpressure in the liver, the liver expands, and 0.5 to 1 liter of extra blood is occasionally stored in the hepatic ...
Some components are synthesized by hepatocytes (liver cells); the rest are extracted from the blood by the liver. [3] Bile is secreted by the liver into small ducts that join to form the common hepatic duct. [4] Between meals, secreted bile is stored in the gallbladder. [5]
Davis acknowledges that this type of behavior on set was "just normal then." "It was normal for a long time. You could look at it either way," she adds. "But I mean, there was a lot of stress. If ...
In normal liver, stellate cells are described as being in a quiescent state. Quiescent stellate cells represent 5-8% of the total number of liver cells. [4] Each cell has several long cytoplasmic protrusions that extend from the cell body and wrap around the sinusoids. [5] The lipid droplets in the cell body store vitamin A as retinyl palmitate ...
