The trachea, commonly known as the windpipe, is the large tube that delivers air from the upper respiratory tract (the nasal passages, throat, and larynx) to the bronchi (the two large airways that branch off into each lung). In the process, it warms and moisturizes the air and catches debris and microbes before they enter the lungs.1
The trachea is vulnerable to infections, inflammation, and other stresses that can damage cells. This can lead to conditions like tracheal stenosis, in which the trachea narrows and restricts breathing, and tracheal cancer, an extremely rare form of cancer.
