The carina is a cartilaginous ridge separating the left and right main bronchi that is formed by the inferior-ward and posterior-ward prolongation of the inferior-most tracheal cartilage. [2] The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra.
Carina Function. When breathing, the carina moves up and down. On a deep inhale, it may move up to 25 mm in adults. The cartilaginous ridges within the trachea serve to reinforce the...

9 Σεπ 2024 · In an adult, the trachea is about 4 to 5 inches long and 1 inch around (diameter). The trachea starts just under the voice box (larynx) and runs down the center of the chest behind the breast bone (sternum) in front of the esophagus. The trachea is connected to the larynx by a ring of cartilage (cricoid cartilage).
The trachea serves as a conduit for ventilation and the clearance of tracheal and bronchial secretions. The trachea begins at the lower border of the cricoid cartilage and extends to the level of the carina . It is composed of C-shaped cartilaginous rings that form the anterior and lateral walls.
Definition. The carina of trachea is a cartilaginous ridge within the trachea that runs antero-posteriorly between the two primary bronchi at the site of the tracheal bifurcation at the lower end of the trachea (usually at the level of the 5th thoracic vertebra, which is in line with the angle of Louis, but may raise or descend up to two ...
