Dislodgement of a foreign body along the respiratory tract
occurs anatomically at
Right main bronchus or lower part of trachea
Left upper anterior bronchus
Nasal turbinates or Laryngopharynx
Bronchus intermedius
E
Lingular segmental bronchus

Right main bronchus or lower part of trachea

Explanation:

To correctly answer this question, one has to know correctly the respiratory tract anatomy.

The air that enters from the atmosphere to our lungs normally takes the following path:

- Nasal or oral cavity. If it enters from the nose, it will pass through the nasal turbinates towards the rhinopharynx, where it will communicate within the oropharynx (in contact with the oral cavity).

- The oropharynx continues inferiorly to the laryngopharynx (remember: the pharynx is composed by three portions: rhino-, oro-, and laryngopharynx, from superior to inferior).

- The laryngopharynx then divides anteriorly towards the larynx and posterior lt towards the esophagus. The larynx is the location where our vocal chords can be found.

- Inferior to the larynx is the trachea, which divides to a right and left main bronchus at the level of the 4th thoracic vertebrae.

Note: the right main bronchus has anatomic characteristics that cause foreign bodies to lodge more frequently here than on the left side. It presents a larger diameter (wider), it is shorter and more vertical than the left main bronchus.
