From the OReilly book the bash shell

One advantage of bash’s ability to look for either synonym is that you
can retain your .profile if you have been using the Bourne shell. If
you need to add bash-specific commands, you can put them in
.bash_profile followed by the command source .profile. When you log
in, all the bash-specific commands will be executed, and bash will
source .profile, executing the remaining commands. If you decide to
switch to using the Bourne shell you don’t have to modify your
existing files. A similar approach was intended for .bash_login and
the C shell .login, but due to differences in the basic syntax of the
shells, this is not a good idea. .bash_profile is read and executed
only by the login shell. If you start up a new shell (a subshell) by
typing bash on the command line, it will attempt to read commands from
the file .bashrc. This scheme allows you the flexibility to separate
startup commands needed at login time from those you might need when
you run a subshell. If you need to have the same commands run
regardless of whether it is a login shell or a subshell, you can just
use the source command from within .bash_profile to execute .bashrc.
If .bashrc doesn’t exist then no commands are executed when you start
up a subshell.
