I. INTRODUCTION
What are Hepatocytes?
Hepatocyte means; “hepato-“ pertaining to the liver, and “-cyte” is a cell.
A hepatocyte is a liver cell. Cells are the smallest functional units of thebody. They combine to make up tissues, which then combine with other tissues to make organs.
Specialized cells, such as hepatocytes, are often given a more specific name.
In the body, diseasehappens at the cellular level.
In this work we will give to know more detail about the Hepatocytes. Why are they important? , On which part of the body are specialized and located?
Some of thosequestions were going to answer so we can have a clear idea of what is the importance of these cells.



II. THEORY
* Mitosis
Biological meaning: All living organisms use cell division,either as playback mechanism, or as a mechanism of growth of the individual. The single-celled beings used cell division for the reproduction and perpetuation of the species, one cell divides into twocells genetically identical daughters and identical to the original, while maintaining the chromosome number and the genetic identity of the species. In multicellular organisms, cell division becomesa cyclical process aimed at the production of multiple cells, all identical between themselves, but that may later result in a specialization and differentiation within the individual. The stage ofmitosis follo interphase. In mitosis the cells nuclear material devides and separate into opposite ends of the cell.
Stage of Mitosis
Prophase the first stage of mitosis- the stage of mitosis duringwhich a dividing cell spends the most time. In this stage the cells choromatine tightens, or condenses, into choromosomes.
Metaphase during the second stage of mitosis, the siter choromatics arepulled by motor proteins along the spindle apparatus toward the center of the cell and line up in the middel of the cell. Is the shortest stage of mitosis.
Anaphase the microtubules of the spindle...
