Cell division continuously replaces worn or damaged cells and supports growth and tissue repair. Scientists estimate that the human body generates hundreds of billions of new cells each day through processes such as mitosis. The production rate varies among tissues because blood, skin, and intestinal cells are renewed more frequently than many other cell types.
