The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
It contains the vestibular folds, and between these and the vocal folds are the laryngeal ventricles. [1] The vestibule is an opening in the lateral wall of the larynx, between the vestibular fold above and the vocal folds below. It is the inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle.
The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. [1] The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.

The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus . The bronchi branch off into smaller sections inside the lungs, called bronchioles .
This marked difference between the composition of the alveolar air and that of the ambient air can be maintained because the functional residual capacity is contained in dead-end sacs connected to the outside air by fairly narrow and relatively long tubes (the airways: nose, pharynx, larynx, trachea, bronchi and their branches down to the ...
The buccopharyngeal fascia is a fascia of the pharynx. [1] It represents the posterior portion of the pretracheal fascia [ 2 ] (visceral fascia) . [ 3 ] It covers the superior pharyngeal constrictor muscles , and buccinator muscle .
