Through which of the following pas of nasal cavity does the main current of airflow occur during inspiration?
Airflow through the nose is a result of pressure difference created by a negative pressure gradient generated by the expanding intrathoracic volume during inspiration. Majority of air flows through the middle meatus of the nasal cavity and takes a parabolic curve, as the airflow curves inferiorly as it passes through the choanae into the nasopharynx.
Through olfactory area
Superior pa of the cavity in the superior meatus
Middle pa of the cavity in middle meatus in a parabolic curve
Lower pa of the cavity in the inferior meatus in a parabolic curve
