An adult's trachea has an inner diameter of about 1.5 to 2 centimetres (1 ⁄ 2 to 3 ⁄ 4 in) and a length of about 10 to 11 cm (4 to 4 + 1 ⁄ 4 in), wider in males than females. [2] The trachea begins at the lower edge of the cricoid cartilage of the larynx [3] at the level of sixth cervical vertebra (C6) [2] and ends at the carina, the ...
The 5 papillae are filiform, fungiform, foliate, vallate, and conical. [2] Papillae allow a cat to groom itself. [3] A cat's sense of smell and taste work closely together, having a vomeronasal organ that allows them to use their tongue as scent tasters, [4] while its longitudinal, transverse, and vertical intrinsic muscles aid in movement.

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 .
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
[2] The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back).
The laryngeal ventricle, (also called the ventricle of the larynx, laryngeal sinus, or Morgagni's sinus) [1] is a fusiform fossa, situated between the vestibular and vocal folds on either side, and extending nearly their entire length. There is also a sinus of Morgagni in the pharynx.

The laryngotracheal groove is a precursor for the larynx and trachea. The rudiment of the respiratory organs appears as a median longitudinal groove in the ventral wall of the pharynx. The groove deepens, and its lips fuse to form a septum, which grows from below upward and converts the groove into a tube, the laryngotracheal tube. The cephalic ...
