Hepatocyte

from Wikipedia, the free encyclopedia

Hepatocytes , and liver cells or hepatocytes called, are about 10 to 30 micrometers large cells that about 80 percent of the liver occupy volume. They come from the endoderm of the intestinal system .

Cell organelles

The hepatocytes are metabolically very active and contain numerous cell organelles :

  • Glycogen fields (the amount of glycogen depends on the diet and is subject to daily fluctuations)

construction

Like all epithelial cells, the hepatocyte has a polarized structure and function. They have a basolateral (sinusoidal) and an apical (canalicular) membrane, but no basal lamina.

The narrow apical bile pole carries numerous microvilli and secretes bile. The broad basolateral blood pole also borders a sinusoid through microvilli and is responsible for the exchange of substances between blood and hepatocyte.

function

The hepatocytes are involved in many metabolic processes and have the following important functions:
