Which cells in a human have the longest lifespan? Which cell has the shortest lifespan?
Some mature neurons can last a lifetime. Gastrointestinal cells such as those in the colon might be shortest-lived, and skin may give them a run for their money. However, depending on how you define lifespan, egg and sperm cells could beat those numbers. Also, some immune cells only last a few days under certain scenarios, such as the aptly-named short-lived plasma cells.
