WebbThe trachea is supported by a series of C-shaped cartilaginous (hyaline cartilage) rings. Dorsally, the ends of the incomplete cartilaginous rings of the trachea are connected by a band of smooth muscle: the trachealis muscle. Externally, the trachea is surrounded by a thin layer of fibrovascular connective tissue (adventitia). Trachea, dog. WebbThe trachealis muscle, composed of smooth muscle, joins the ends of the tracheal cartilage rings. It contains stretch receptors that respond to transverse strain and thus is responsible for changing trachea diameter (Bartlett et al., 1976).

WebbIt is a part of the lower respiratory tract and connects the larynx to the lungs through the bronchial tree. In adults, the diameter of the trachea is about 0.6 - 1 inches (1.5 - 2.5 cm), and it is around 4 - 5 inches (10 - 13 cm) long.
