Basic human airway anatomy. Objects can enter the trachea and lungs via the mouth or nose. Signs and symptoms of foreign body aspiration vary based on the site of obstruction, the size of the foreign body, and the severity of obstruction. [2] 20% of foreign bodies become lodged in the upper airway, while 80% become lodged in a bronchus. [6]
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
During sneezing, it protects the nasal passage by diverting a portion of the excreted substance to the mouth. In humans , the uvula hangs from the end of the soft palate. Touching the uvula or the end of the soft palate evokes a strong gag reflex in most people.
In contrast, however, mouth breathing "pulls all pollution and germs directly into the lungs; dry cold air in the lungs makes the secretions thick, slows the cleaning cilia, and slows down the passage of oxygen into the bloodstream". [15] As a result, chronic mouth breathing may lead to illness.
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
