epiglottis
The trachea is made of C shaped rings of cartilage, this maintains the shape of the trachea.
The trachea is maintained in an open position by C-shaped rings of hyaline cartilage along its walls. These rings provide structural support to prevent collapse during breathing while allowing flexibility for movement and expansion.
The epiglottis is the flap of tissue that prevents food and liquid from entering the windpipe (trachea) when you swallow. It acts like a lid over the windpipe, directing food and liquid down the esophagus to the stomach.
Nasal patentency refers to lack of nasal obstruction; a patent nostil means there is nothing occluding the airway like a nasal polyp --> nasal airway is clear is it is patent
The singular for trachea is "trachea". The plural is "tracheae".
The cartilage surrounding the trachea and bronchi provides structural support, keeping these airways open and preventing collapse during breathing. This rigid framework allows for flexibility and movement while maintaining a clear passage for airflow. Additionally, it helps protect the airways from injury and maintains the integrity of the respiratory system.

No trachea is not the lung.
tThe trachea ends at the bronchia which takes air from the trachea to the lungs.
That tube is the trachea.
