Published	02/10/2024	The trachea is a wide flexible tube that contains {{c1::20 C-shaped tracheal cartilages}}, which are hyaline in nature, keeps the lumen patent.
Published	02/10/2024	The gaps between the rings of cartilage are filled by the {{c1::trachealis}} muscle and {{c1::fibroelastic}} tissue.
Published	02/10/2024	The respiratory mucosa and submucosa are adapted to {{c1::warm and moisten}} the air, and to {{c1::trap foreign particles}} in mucous.
Published	02/10/2024	The mucosal layer of the Trachea contains {{c1::ciliated pseudostratified columnar}} epithelium with {{c1::goblet}} cells.
Published	02/10/2024	The submucosal layer of the Trachea contains {{c1::mixed-seromucous glands}} for humidification and trapping particles and bacteria.
Published	02/10/2024	The {{c1::adventitia}} layer of the Trachea connects and supports it to surrounding tissue.• Contains nerves, vessels and adipose tissue.
