LARYNX, TRACHEA

Larynx. Organ of the upper airways located between the pharynx and the trachea. It carries out two crucial functions: 1) phonation, 2) partition of airways and digestive pathways. It is constituted by several cartilaginous and fibrous structures: epiglottis, glottis and vocal chords.

Trachea. Tubular hollow organ. It is a portion of the airways located between the larynx and the two main bronchia. The trachea is 12 cm long and has a diameter of about 1.5-2.5 cm. The trachea wall is constituted by a flexible fibrous membrane that is kept expanded by approximately 16-20 cartilaginous rings.

The projections of the larynx and the trachea are found in the upper portion of the nasal sectors in continuity with the projections of tonsils, oral cavity and pharynx (fourth and fifth circular rings).
