Be careful that some of those files explicitly include others. For example my (default) ~/.profile includes ~/.bashrc, my ~/.bash_profile includes ~/.profile, /etc/profile includes /etc/bash.bashrc...
So your capture here doesn't show only the files that bash itself decided to load. You also won't see the fallback files (e.g. bash will open .profile if .bash_profile doesn't exist).
