Why can’t limbs grow back?

Can your heart regenerate itself?

The heart is unable to regenerate heart muscle after a heart attack and lost cardiac muscle is replaced by scar tissue. Scar tissue does not contribute to cardiac contractile force and the remaining viable cardiac muscle is thus subject to a greater hemodynamic burden.

How often is the stomach lining replaced?
