nasopharynx
breath air goes through
The nasopharynx is the uppermost part of the throat, lying behind the nasal cavity and above the soft palate. It is also known as the nasal pharynx. The nasopharynx is important for the respiratory and digestive systems as it serves as a passageway for air, food and drink. It is lined with mucous membranes and contains several structures such as the adenoids (pharyngeal tonsils), the Eustachian tubes, and the openings of the auditory tubes. The adenoids are masses of lymphoid tissue that help to defend against infections, while the Eustachian tubes connect the middle ear to the nasopharynx and help to equalize pressure in the ear. Infections of the nasopharynx can cause discomfort and may result in symptoms such as sore throat, runny nose, congestion, and coughing.
