Where in the human body would you look for cells undergoing Mitosis? Explain.?

I learned about this in science. Mitosis is the stage a cell undergoes when it is getting ready to pop in half. Everything doubles and both of the daughter cells have the same number of cells as the original cell. All living cells in your body undergo mitosis to reproduce, so anywhere is fine. I can remember that the liver cells undergo the cell cycle in 22 hours so that might be a good place.
