What is the trachea?

The trachea is that part of the respiratory system that connects the larynx and the initial part of the bronchi . The trachea undergoes a bifurcation near the fifth dorsal vertebra , where it is divided into the left and right bronchial trees . The bronchial bifurcation is called the hull or tracheal spur . The trachea allows the passage of air.

What is the trachea?

The trachea is an organ about 12 cm long , cylindrical in shape and located in front of the esophagus . The trachea is a cartilaginous organ, in that it is made up of cartilages in the shape of a horseshoe arranged horizontally and superimposed on each other. The tracheal ligaments , or annular ligaments , contribute to the composition of this organ, as are fibrous structures that appear between a cartilage and the other. The posterior part of the trachea is closed by a muscle tissue , and composed of the openings of the cartilages. The tissue that forms it is fibrocartilaginous . In the internal part of the trache the walls are covered with mucosa.

There are various diseases that can affect it: the most common are tracheitis , infections that can occur in an acute or chronic form, the factors of which can be viral, bacterial, allergic.

What is the trachea for?

Its fundamental task is to allow the passage of air that reaches the bronchi from the larynx .
