oropharynx
the area directly posterior to the mouth
The oropharynx is a part of the pharynx (throat) located behind the oral cavity (mouth). It extends from the uvula to the level of the hyoid bone. The oropharynx serves as a common passageway for food and air and is involved in the process of digestion and respiration.
The oropharynx is lined with a mucous membrane that is continuous with the lining of the mouth and larynx. The mucous membrane contains numerous lymphoid follicles, which are involved in the immune response to pathogens.
Functions of the oropharynx include:
1. Swallowing: Food and liquids pass through the oropharynx on their way to the esophagus.
2. Breathing: Air passes through the oropharynx on its way to the trachea.
3. Speech: The oropharynx plays an important role in producing speech by shaping the sound waves generated by the vocal cords.
4. Immune function: The lymphoid tissue in the oropharynx helps to protect the body against infections and other pathogens.
Diseases and conditions that affect the oropharynx include pharyngitis (inflammation of the pharynx), tonsillitis (inflammation of the tonsils), and cancer. Chronic smoking and alcohol use are risk factors for developing cancer of the oropharynx.
