>From the Bash man page:
       Non-login interactive shells:
         On startup (subject to the -norc and -rcfile options):
               if ~/.bashrc exists, source it.

       Non-interactive shells:
         On startup:
               if the environment variable ENV is non-null, expand
               it and source the file it names, as if the command
                       if [ "$ENV" ]; then . $ENV; fi
               had been executed, but do not use PATH to search
               for the pathname.  When not started in Posix mode, bash
               looks for BASH_ENV before ENV.

Emacs starts Bash as "Non-login interactive shells". To make thing
easier I suggest you set "BASH_ENV" to "/etc/profile" in ~/.emacs:
    (setenv "BASH_ENV" "/etc/profile")
