why is my $PATH much longer than .bash_profile

echo $PATH shows:

/usr/local/bin:/opt/local/bin:/opt/local/sbin://anaconda/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/Users/stefankaros/bin/FDK/Tools/osx

my ~/.bash_profile is:

# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

# added by Anaconda 2.0.1 installer
export PATH="//anaconda/bin:$PATH"

# Initialization for FDK command line tools.Tue Oct  7 20:01:15 2014
FDK_EXE="/Users/stefankaros/bin/FDK/Tools/osx"
PATH=${PATH}:"/Users/stefankaros/bin/FDK/Tools/osx"
export PATH
export FDK_EXE

# MacPorts Installer addition on 2014-10-22_at_21:44:05: adding an appropriate PATH variable for use with MacPorts.
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
# Finished adapting your PATH environment variable for use with MacPorts.

export PATH=/usr/local/bin:$PATH

I do not have .bashrc or any other file that starts with .bash in my home dir. in my PATH,where does the opt/x11/bin come from? why is use/bin duplicated? In my .bash_profile, what does export FDK_exe do? PATH was just exported in the line before?

On Mac OS X, there is a file /etc/paths which contains (on my Yosemite machine):

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

These are the elements on your PATH that you don't set explicitly in your .bash_profile. There's also a directory /etc/paths.d but that's empty on my machine. See also man path_helper and /usr/libexec/path_helper, called from /etc/profile.

You could clean up your PATH to remove duplicate elements. See How to keep from duplicating PATH variable in csh — which has relevant answers even if you use Bourne shell derivatives.
