Do human cells change every 11 months?

Answer 1

Depends on what you mean by change. Most cells are constantly dying and recreating, such as the cells making up the stomach lining(only have a life span of about 3 days). Brain cells on the other hand are created at birth and start dying off around 65 yrs. So for the most part all your cells change up every 11 months but not absolutely all of the cells.
