All the cells in our body have a certain lifespan, i.e., they only replicate a given number of times before they enter senescence and eventually die. Given that different kinds of cells have different lifespans, the sum of the whole human body lives considerably longer than any individual cell. So how long does it take for all of the cells in the body to have changed over at least one time? Is it a period of months, or years?
Re: How often are all the cells in our bodies replaced?
