The trachea begins at the level of the sixth cervical vertebra and in the adult extends for approximately 11 cm to the fifth thoracic vertebra. There it divides into the right and left mainstem bronchi, one for each lung (Figure 1-9). The point of division is called the carina. Inspired air becomes 100% saturated with water vapor and is warmed to body temperature (37?C) after it passes through two or three airway subdivisions below the carina.
