Trachea

January 2017


Definition

The trachea is one of the organs of the respiratory system: it is a kind of large tube a few inches in length that connects the larynx (at the back of the throat) to the bronchi. Its role is to provide air that has previously been filtered, therefore oxygen, to the bronchi (during inspiration) and to release the air laden with carbon dioxide that is rejected by the lungs (during expiration). The trachea is covered with a very thin fragile mucosa. Inflammation of this organ is called tracheitis.
