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. It's used when a tumor or other condition blocks an airway. In children, the procedure most often is used to remove something blocking an airway.
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.
Multiplied by 3,000,000, that is 1,875,000 miles of lake shoreline!!! And this is the minimum measure! As you can see, if you add lake shoreline to coastline, Alaska has considerably more total shoreline than Minnesota's claim of 90,000 miles, though the actual number is not very clear. If Alaska has 3,000,000 20+ acre lakes, then by the math above, Alaska has at least 1,922,300 miles of shoreline.
