How cell division is important for replacement and repair give specific examples?

Cell division is crucial for replacement and repair as it enables the production of new cells to replace those that are damaged or lost. For instance, when skin cells are injured from a cut, mitosis allows for the rapid generation of new cells to heal the wound. Similarly, in the case of red blood cells, which have a limited lifespan of about 120 days, continuous cell division in the bone marrow produces new cells to maintain adequate oxygen transport in the body.
