does the human digestive system grow as you grow?
well I don't know, that's why I'm asking you and besides an adults digestive system is probably 20-30 feet long and ababy might be 1/4 size of that mens the baby's digestive system is 5-7.5 ft. long.
well OBVIOUSLY. think about how tiny babies are -- do you honestly believe that their digestive system stays THAT small for their whole life ??
Yes, it does, in length & width.
