Trachea
The trachea is an extrapulmonary component of the conducting portion, continuing inferiorly from the larynx. It lies anterior to the esophagus and its walls are supported by C-shaped cartilage rings, whose openings face the esophagus. The two main lobes of the thyroid gland are visible at the lateral boundaries of the trachea. The trachea is about 2.5 cm in diameter and 10-12 cm long. It bifurcates into left and right primary (main) bronchi which enter the lung. The histological structure of the trachea and main bronchi is similar. 10x
