The Nose The nose, a prominent feature of the face, is the only external portion of the respiratory system. Air enters the nose through external openings called nostrils. The nose contains two nasal cavities, which are narrow canals separated from one another by a septum composed of bone and cartilage (Fig. 14.2). Mucous membrane lines the nasal cavities.
