Why does the get_item_html have 2 parameters?

In the function that ouputs the html for the catalog pages, it's been set up to take 2 paramentes: $id and $item, but the $id is not referenced in the output code. I don't understand why there's 2 parameters being used here. 

// Outputs the HTML for our catalog
function get_item_html($id, $item) {
  $output = "<li><a href='#'><img src='{$item['img']}' alt='{$item['title']}'>View Details</a></li>";
  return $output;
}

    foreach($categories as $id) {
        echo get_item_html ($id, $catalog[$id]);
      }

I've tested it without the $id parameter and it works fine.
