Boogers do not usually choke the airway because the airway itself has normal defenses and most of them adhere to the nasal hairs and do not enter the airway. Boogers are dry crusts of nasal secretions, mostly associated with dryness of the nasal mucosa, etc. They are mainly located in the vestibular region of the nose and most of them adhere to the nasal hairs. The crusts in the nose can usually be cleared out by blowing the nose, but sometimes when blowing the nose and inhaling hard, the crusts may be inhaled into the posterior nostril, resulting in the crusts entering into the throat, and sometimes choking occurs due to misinhalation, but because of the normal defense function of the airway, it will not enter into the trachea. As you can see, boogers usually do not enter the trachea, and it is recommended that you do not inhale when blowing your nose, and gently clean the boogers.
