A plaintiff from Stevens Point files a complaint in federal court, if she is filing in the federal court that includes Portage County in its jurisdiction, what is the name of the court she would file in? (note: I am looking for the name of the court in the federal court system, not the name of the courthouse or federal building where the court is located):

The plaintiff from the prior question loses his case at the trial court level and decides to appeal. With what court would the plaintiff file his appeal? (again, the name of the court in the federal court system, not the name of the courthouse or federal building where the court is located).
