drupal_get_form in includes/form.inc: Processes a form array and produces the HTML output of a form. If there is input in the $_POST['edit'] variable, this function will attempt to validate it, using drupal_validate_form(), and then submit the form using drupal_submit_form().
form_builder in includes/form.inc: Adds some required properties to each form element, which are used internally in the form api. This function also automatically assigns the value property from the $edit array, provided the element doesn't already have an assigned value.
