Sometimes bronchoscopy is used to treat lung problems. It may be done to insert a stent in an airway. An airway stent is a small tube that holds the airway open.

Spanning the border from Minnesota into the Canadian provinces of Ontario and Manitoba, Lake of the Woods is an enormous body of water over 68 miles long, 59 miles wide, with 25,000 miles of shoreline-the world's longest lake shoreline.

The largest lake entirely contained in the United States is Lake Michigan, 22,400 square miles. Excluding the great lakes, the Great Salt Lake in Utah is the largest lake in the USA at 1700 square miles.
