The two nasal chambers are continuous posteriorly with a single cavity known as the nasopharynx.

Pharyngeal Tonsils Tab:
The pharyngeal tonsils are a pair of lymphoid aggregates in the upper posterior recess of the nasopharynx.

Auditory Tubes Tab :
On each lateral wall of the nasopharynx is a small mound with a slit-like opening. This is the opening of the auditory tube, which passes laterally to the middle ear cavity.

Because of this tube, the air pressures are kept equal on the inner and outer sides of the tympanic membrane.

Soft Palate Tab:
The floor of the nasopharynx is the soft palate. The soft palate is a musculomembranous structure. The nasopharynx (of the respiratory system) and the oropharynx (of the digestive system) are continuous posteriorly with the pharynx proper.

During swallowing, the soft palate is raised like a trap door to close off the upper air passageways. This prevents movement of food into the upper air passageways.
