Hepatocytes constitute about 80% of the cell population of the liver, with the other 20% being occupied by Kupffer cells, hepatic stellate cells, endothelial cells and mesothelial cells, which are not exactly characteristic of the liver, but are present in the liver samples. [2] Histologically speaking, hepatocytes have specific characteristics.
The typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types. [3]
The degree of rise in conjugated bilirubin is directly proportional to the degree of hepatocyte injury. Viral hepatitis can also cause the rise in conjugated bilirubin. In parenchymal liver disease and incomplete extrahepatic obstruction, the rise in conjugated bilirubin is less than the complete common bile duct obstruction due to malignant ...
Many people believe that yellow or green mucus indicates a bacterial infection, but experts caution that color doesn’t correlate to a particular type of infection, as both viruses and bacteria ...
About 70–85% of the liver volume is occupied by parenchymal hepatocytes. Nonparenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [27] The liver sinusoids are lined with two types of cell, sinusoidal endothelial cells, and phagocytic Kupffer cells. [28]

Overview of phagocytosis Phagocytosis versus exocytosis. Phagocytosis (from Ancient Greek φαγεῖν (phagein) ' to eat ' and κύτος (kytos) ' cell ') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome.
