The inner mucosal layer has a lining of ciliated pseudostratified columnar epithelium with goblet cells. The posterior aspect of the trachea is adjacent to the anterior esophagus. A narrow thin membrane connects each of the tracheal rings. The trachea is 16 to 20 C-shaped cartilage rings stacked one on top of another. It is much broader in the proximal area than the distal segment. The tracheal diameter is about 24 to 26 mm in adult males and 22 to 24 mm in females. This junction point is called the carina. The trachea is a midline structure and lies just anterior the esophagus.Īfter it originates from the larynx, the trachea divides into the left and right mainstem bronchi. The primary function of the trachea is to allow passage of inspired and expired air into and out of the lung. Common asthma triggers.The trachea originates at the inferior edge of the larynx and connects to the left and main stem bronchus.
