Because epithilial cells usually flakes away.So always have to be replaced.Liver cells do not damaged easily.
Most of the intestinal epithelial cells would likely be in the G1 phase of the cell cycle, as they are constantly renewing and dividing to maintain the integrity of the intestinal lining.
The fastest dividing cells are typically found in rapidly regenerating tissues, such as epithelial cells lining the gut or skin, or in certain types of stem cells. These cells have a short cell cycle and quickly go through the stages of division to replenish tissues.
The cells are alive and metabolically active.
In the cell cycle of cancer cells interphase is still the longest phase. However, interphase is shorter in cancer cells than in normal cells.
The type of cells that do not undergo mitosis are the cells in the human body that are considered to be terminally differentiated, such as nerve cells and muscle cells. These cells have exited the cell cycle and do not divide further.
Vaginal epithelial cells in the estrous cycle are most commonly observed during the proestrus stage. This is when the cells undergo changes in preparation for estrus, such as an increase in the number of cornified epithelial cells. Dinoflagellate cells are also sometimes seen during this stage.
Most of the intestinal epithelial cells would likely be in the G1 phase of the cell cycle, as they are constantly renewing and dividing to maintain the integrity of the intestinal lining.
Nerve and muscle cells permanently leave the cell cycle because they have exited the cell cycle and differentiated into their specific functions. These cells have reached a state of maturity where they are specialized for their roles in transmitting signals (nerve cells) or generating force (muscle cells), and no longer require division for growth or repair.
Cancer cells often have mutations that disrupt normal cell cycle regulation, leading to uncontrolled cell growth and division. This disruption can cause cancer cells to divide more rapidly, resulting in a shorter cell cycle compared to normal cells.
* Blood cells * Skin cells * Nerve cells (neurons) * Goblet cells (in the lining of the stomach) * Muscle cells * Gametes (female ova or male sperm)Epithelial cells play many very important roles in the human body. they are usually arranged in thin sheets of epithelial tissue and they cover internal and external surfaces. epithelial cells have many different functions, and their basic structure may be adapted to make them more efficient at their job. many epithelial cells are there to protect the tissues underneath from damage or infection.
beats me lol stupid science questions

The syntthesis (s) stage.
Most differentiated cells in the human body tend to rarely undergo mitosis, including nerve cells (neurons) and muscle cells (myocytes). These cells have exited the cell cycle and are in a specialized state, focusing on carrying out their specific functions.
