The trachea (also known as a windpipe) is made up of hard rings of cartilage and carries air from the nose and throat to small airways (bronchi) that go to the lungs. Tracheal collapse is a common cause of airway obstruction that occurs when these rings of cartilage collapse.he trachea (also known as a windpipe) is made up of hard rings of cartilage and carries air from the nose and throat to small airways (bronchi) that go to the lungs.
