Why do i have a form url point at thesame location but not at a specific file that will insert my data into database

My LoginUser.blade.php

<h1>Login</h1>

{{-- Form start comment --}}

    {{ Form::open(array('url' => 'user/loginUser')) }}

        <p>         
            {{ Form::label('email', 'E-Mail Address') }}
            {{ Form::email('email', null, array("placeholder" => "Enter your email")) }}
        </p>

        <p>         
            {{ Form::label('password', 'Password') }}
            {{ Form::password('password', array("placeholder"=>"Enter your password")) }}
        </p>

        <p>         
            {{ Form::submit('Sign In') }}
        </p>

    {{ Form::close() }}

{{-- Form end comment --}}

So my Question is why should my URL points to my current LoginUser.blade.php which contains the HTML forms?? Please am new to laravel am using laravel 5.2
