The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum).The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. Tracheal foreign body: An object is inhaled (aspirated) and lodges in the trachea or one of its branches. 2  A procedure called bronchoscopy is usually needed to remove a foreign body from the trachea. 3  Tracheal cancer: Cancer of the trachea is quite rare. 4  Symptoms can include coughing or difficulty breathing.
